+ * In this example, if you try to use a class in the Symfony\Component

+ *
+ * This class is loosely based on the Symfony UniversalClassLoader.

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+HTML Purifier [![Build Status](https://github.com/ezyang/htmlpurifier/actions/workflows/ci.yml/badge.svg?branch=master)](https://github.com/ezyang/htmlpurifier/actions/workflows/ci.yml)
+=============
+
+HTML Purifier is an HTML filtering solution that uses a unique combination
+of robust whitelists and aggressive parsing to ensure that not only are
+XSS attacks thwarted, but the resulting HTML is standards compliant.
+
+HTML Purifier is oriented towards richly formatted documents from
+untrusted sources that require CSS and a full tag-set.  This library can
+be configured to accept a more restrictive set of tags, but it won't be
+as efficient as more bare-bones parsers. It will, however, do the job
+right, which may be more important.
+
+Places to go:
+
+* See INSTALL for a quick installation guide
+* See docs/ for developer-oriented documentation, code examples and
+  an in-depth installation guide.
+* See WYSIWYG for information on editors like TinyMCE and FCKeditor

+            //    legitimate font-name
+            //    <http://ja.wikipedia.org/wiki/MS_明朝>.  See

+            //    You can see live samples of these on the Internet:
+            //    <http://www.google.co.jp/search?q=font-family+ＭＳ+明朝|ゴシック>
+            //    However, most of these fonts have ASCII equivalents:
+            //    for example, 'MS Mincho', and it's considered
+            //    professional to use ASCII font names instead of
+            //    Unicode font names.  Thanks Takeshi Terada for
+            //    providing this information.
+            //  The following characters, to my knowledge, have not been
+            //  used to name font names.
+            //  - Single quote.  While theoretically you might find a
+            //    font name that has a single quote in its name (serving
+            //    as an apostrophe, e.g. Dave's Scribble), I haven't
+            //    been able to find any actual examples of this.
+            //    Internet Explorer's cssText translation (which I
+            //    believe is invoked by innerHTML) normalizes any
+            //    quoting to single quotes, and fails to escape single
+            //    quotes.  (Note that this is not IE's behavior for all
+            //    CSS properties, just some sort of special casing for
+            //    font-family).  So a single quote *cannot* be used
+            //    safely in the font-family context if there will be an
+            //    innerHTML/cssText translation.  Note that Firefox 3.x
+            //    does this too.
+            //  - Double quote.  In IE, these get normalized to
+            //    single-quotes, no matter what the encoding.  (Fun
+            //    fact, in IE8, the 'content' CSS property gained
+            //    support, where they special cased to preserve encoded
+            //    double quotes, but still translate unadorned double
+            //    quotes into single quotes.)  So, because their
+            //    fixpoint behavior is identical to single quotes, they
+            //    cannot be allowed either.  Firefox 3.x displays
+            //    single-quote style behavior.
+            //  - Backslashes are reduced by one (so \\ -> \) every
+            //    iteration, so they cannot be used safely.  This shows
+            //    up in IE7, IE8 and FF3
+            //  - Semicolons, commas and backticks are handled properly.
+            //  - The rest of the ASCII punctuation is handled properly.
+            // We haven't checked what browsers do to unadorned
+            // versions, but this is not important as long as the
+            // browser doesn't /remove/ surrounding quotes (as IE does
+            // for HTML).
+            //
+            // With these results in hand, we conclude that there are
+            // various levels of safety:
+            //  - Paranoid: alphanumeric, spaces and dashes(?)
+            //  - International: Paranoid + non-ASCII Unicode
+            //  - Edgy: Everything except quotes, backslashes
+            //  - NoJS: Standards compliance, e.g. sod IE. Note that
+            //    with some judicious character escaping (since certain
+            //    types of escaping doesn't work) this is theoretically
+            //    OK as long as innerHTML/cssText is not called.
+            // We believe that international is a reasonable default
+            // (that we will implement now), and once we do more
+            // extensive research, we may feel comfortable with dropping
+            // it down to edgy.
+
+            // Edgy: alphanumeric, spaces, dashes, underscores and Unicode.  Use of

+ * Definition for tables.  The general idea is to extract out all of the

+ *
+ * This is a bit confusing, because the DTDs and the W3C
+ * validators seem to disagree on the appropriate definition. The
+ * DTD claims:
+ *
+ *      (CAPTION?, (COL*|COLGROUP*), THEAD?, TFOOT?, TBODY+)
+ *
+ * But actually, the HTML4 spec then has this to say:
+ *
+ *      The TBODY start tag is always required except when the table
+ *      contains only one table body and no table head or foot sections.
+ *      The TBODY end tag may always be safely omitted.
+ *
+ * So the DTD is kind of wrong.  The validator is, unfortunately, kind
+ * of on crack.
+ *
+ * The definition changed again in XHTML1.1; and in my opinion, this
+ * formulation makes the most sense.
+ *
+ *      caption?, ( col* | colgroup* ), (( thead?, tfoot?, tbody+ ) | ( tr+ ))
+ *
+ * Essentially, we have two modes: thead/tfoot/tbody mode, and tr mode.
+ * If we encounter a thead, tfoot or tbody, we are placed in the former
+ * mode, and we *must* wrap any stray tr segments with a tbody. But if
+ * we don't run into any of them, just have tr tags is OK.

+Lookup table of all allowed link frame targets.  Some commonly used link
+targets include _blank, _self, _parent and _top. Values should be
+lowercase, as validation will be done in a case-sensitive manner despite
+W3C's recommendation. XHTML 1.0 Strict does not permit the target attribute
+so this directive will have no effect in that doctype. XHTML 1.1 does not
+enable the Target module by default, you will have to manually enable it
+(see the module documentation for more details.)

+If null, class will auto-detect the doctype and, if matching XHTML 1.1 or

+is forced; if false, the NMTOKENS definition is forced.  To get behavior
+of HTML Purifier prior to 4.0.0, set this directive to false.
+
+Some rational behind the auto-detection:
+in previous versions of HTML Purifier, it was assumed that the form of
+class was NMTOKENS, as specified by the XHTML Modularization (representing
+XHTML 1.1 and XHTML 2.0).  The DTDs for HTML 4.01 and XHTML 1.0, however
+specify class as CDATA.  HTML 5 effectively defines it as CDATA, but
+with the additional constraint that each name should be unique (this is not
+explicitly outlined in previous specifications).

+AutoFormat.RemoveEmpty
+TYPE: bool
+VERSION: 3.2.0

+--DESCRIPTION--
+<p>
+  When enabled, HTML Purifier will attempt to remove empty elements that
+  contribute no semantic information to the document. The following types
+  of nodes will be removed:
+</p>
+<ul><li>
+    Tags with no attributes and no content, and that are not empty
+    elements (remove <code>&lt;a&gt;&lt;/a&gt;</code> but not
+    <code>&lt;br /&gt;</code>), and
+  </li>
+  <li>
+    Tags with no content, except for:<ul>
+      <li>The <code>colgroup</code> element, or</li>
+      <li>
+        Elements with the <code>id</code> or <code>name</code> attribute,
+        when those attributes are permitted on those elements.
+      </li>
+    </ul></li>
+</ul>
+<p>
+  Please be very careful when using this functionality; while it may not
+  seem that empty elements contain useful information, they can alter the
+  layout of a document given appropriate styling. This directive is most
+  useful when you are processing machine-generated HTML, please avoid using
+  it on regular user HTML.
+</p>
+<p>
+  Elements that contain only whitespace will be treated as empty. Non-breaking
+  spaces, however, do not count as whitespace. See
+  %AutoFormat.RemoveEmpty.RemoveNbsp for alternate behavior.
+</p>
+<p>
+  This algorithm is not perfect; you may still notice some empty tags,
+  particularly if a node had elements, but those elements were later removed
+  because they were not permitted in that context, or tags that, after
+  being auto-closed by another tag, where empty. This is for safety reasons
+  to prevent clever code from breaking validation. The general rule of thumb:
+  if a tag looked empty on the way in, it will get removed; if HTML Purifier
+  made it empty, it will stay.

+  counter measures: an explicit width and height set to auto in all
+  images in your document (unlikely) or the disabling of width and

+    of browsable external resources, which could break things if your redirection
+    script was a splash page or used <code>meta</code> tags. To revert to
+    previous behavior, please use %URI.MungeResources.
+</p>
+<p>
+    You may want to also use %URI.MungeSecretKey along with this directive
+    in order to enforce what URIs your redirector script allows. Open
+    redirector scripts can be a security risk and negatively affect the
+    reputation of your domain name.
+</p>
+<p>
+    Starting with HTML Purifier 3.1.1, there is also these substitutions:

+            <td>1 - The URI embeds a resource<br />(blank) - The URI is merely a link</td>
+            <td></td>
+        </tr>
+        <tr>
+            <td>%n</td>

+            <td></td>
+        </tr>
+    </tbody>
+</table>
+<p>
+    Admittedly, these letters are somewhat arbitrary; the only stipulation
+    was that they couldn't be a through f. r is for resource (I would have preferred
+    e, but you take what you can get), n is for name, m
+    was picked because it came after n (and I couldn't use a), p is for
+    property.

+URI.MungeSecretKey
+TYPE: string/null
+VERSION: 3.1.1
+DEFAULT: NULL
+--DESCRIPTION--
+<p>
+    This directive enables secure checksum generation along with %URI.Munge.
+    It should be set to a secure key that is not shared with anyone else.
+    The checksum can be placed in the URI using %t. Use of this checksum
+    affords an additional level of protection by allowing a redirector
+    to check if a URI has passed through HTML Purifier with this line:
+</p>
+
+<pre>$checksum === hash_hmac("sha256", $url, $secret_key)</pre>
+
+<p>
+    If the output is TRUE, the redirector script should accept the URI.
+</p>
+
+<p>
+    Please note that it would still be possible for an attacker to procure
+    secure hashes en-mass by abusing your website's Preview feature or the
+    like, but this service affords an additional level of protection
+    that should be combined with website blacklisting.
+</p>
+
+<p>
+    Remember this has no effect if %URI.Munge is not on.

+TYPE: string/null

+DEFAULT: NULL
+--DESCRIPTION--
+<p>
+    A PCRE regular expression that will be matched against an iframe URI.  This is
+    a relatively inflexible scheme, but works well enough for the most common
+    use-case of iframes: embedded video.  This directive only has an effect if
+    %HTML.SafeIframe is enabled.  Here are some example values:
+</p>
+<ul>
+    <li><code>%^http://www.youtube.com/embed/%</code> - Allow YouTube videos</li>
+    <li><code>%^http://player.vimeo.com/video/%</code> - Allow Vimeo videos</li>
+    <li><code>%^http://(www.youtube.com/embed/|player.vimeo.com/video/)%</code> - Allow both</li>
+</ul>
+<p>
+    Note that this directive does not give you enough granularity to, say, disable
+    all <code>autoplay</code> videos.  Pipe up on the HTML Purifier forums if this
+    is a capability you want.

+/**
+ * Forgivingly lexes HTML (SGML-style) markup into tokens.
+ *
+ * A lexer parses a string of SGML-style markup and converts them into
+ * corresponding tokens.  It doesn't check for well-formedness, although its
+ * internal mechanism may make this automatic (such as the case of
+ * HTMLPurifier_Lexer_DOMLex).  There are several implementations to choose
+ * from.
+ *
+ * A lexer is HTML-oriented: it might work with XML, but it's not
+ * recommended, as we adhere to a subset of the specification for optimization
+ * reasons. This might change in the future. Also, most tokenizers are not
+ * expected to handle DTDs or PIs.
+ *
+ * This class should not be directly instantiated, but you may use create() to
+ * retrieve a default copy of the lexer.  Being a supertype, this class
+ * does not actually define any implementation, but offers commonly used
+ * convenience functions for subclasses.
+ *
+ * @note The unit tests will instantiate this class for testing purposes, as
+ *       many of the utility functions require a class to be instantiated.
+ *       This means that, even though this class is not runnable, it will
+ *       not be declared abstract.
+ *
+ * @par
+ *
+ * @note
+ * We use tokens rather than create a DOM representation because DOM would:
+ *
+ * @par
+ *  -# Require more processing and memory to create,
+ *  -# Is not streamable, and
+ *  -# Has the entire document structure (html and body not needed).
+ *
+ * @par
+ * However, DOM is helpful in that it makes it easy to move around nodes
+ * without a lot of lookaheads to see when a tag is closed. This is a
+ * limitation of the token system and some workarounds would be nice.

+/**
+ * Parser that uses PHP 5's DOM extension (part of the core).
+ *
+ * In PHP 5, the DOM XML extension was revamped into DOM and added to the core.
+ * It gives us a forgiving HTML parser, which we use to transform the HTML
+ * into a DOM, and then into the tokens.  It is blazingly fast (for large
+ * documents, it performs twenty times faster than
+ * HTMLPurifier_Lexer_DirectLex,and is the default choice for PHP 5.
+ *
+ * @note Any empty elements will have empty tokens associated with them, even if
+ * this is prohibited by the spec. This is cannot be fixed until the spec
+ * comes into play.
+ *
+ * @note PHP's DOM extension does not actually parse any entities, we use
+ *       our own function to do that.
+ *
+ * @warning DOM tends to drop whitespace, which may wreak havoc on indenting.
+ *          If this is a huge problem, due to the fact that HTML is hand
+ *          edited and you are unable to get a parser cache that caches the
+ *          the output of HTML Purifier while keeping the original HTML lying
+ *          around, you may want to run Tidy on the resulting output or use
+ *          HTMLPurifier_DirectLex

+// Note [Injector skips]
+// ~~~~~~~~~~~~~~~~~~~~~
+// When I originally designed this class, the idea behind the 'skip'
+// property of HTMLPurifier_Token was to help avoid infinite loops
+// in injector processing.  For example, suppose you wrote an injector
+// that bolded swear words.  Naively, you might write it so that
+// whenever you saw ****, you replaced it with <strong>****</strong>.
+//
+// When this happens, we will reprocess all of the tokens with the
+// other injectors.  Now there is an opportunity for infinite loop:
+// if we rerun the swear-word injector on these tokens, we might
+// see **** and then reprocess again to get
+// <strong><strong>****</strong></strong> ad infinitum.
+//
+// Thus, the idea of a skip is that once we process a token with
+// an injector, we mark all of those tokens as having "come from"
+// the injector, and we never run the injector again on these
+// tokens.
+//
+// There were two more complications, however:
+//
+//  - With HTMLPurifier_Injector_RemoveEmpty, we noticed that if
+//    you had <b><i></i></b>, after you removed the <i></i>, you
+//    really would like this injector to go back and reprocess
+//    the <b> tag, discovering that it is now empty and can be
+//    removed.  So we reintroduced the possibility of infinite looping
+//    by adding a "rewind" function, which let you go back to an
+//    earlier point in the token stream and reprocess it with injectors.
+//    Needless to say, we need to UN-skip the token so it gets
+//    reprocessed.
+//
+//  - Suppose that you successfuly process a token, replace it with
+//    one with your skip mark, but now another injector wants to
+//    process the skipped token with another token.  Should you continue
+//    to skip that new token, or reprocess it?  If you reprocess,
+//    you can end up with an infinite loop where one injector converts
+//    <a> to <b>, and then another injector converts it back.  So
+//    we inherit the skips, but for some reason, I thought that we
+//    should inherit the skip from the first token of the token
+//    that we deleted.  Why?  Well, it seems to work OK.
+//
+// If I were to redesign this functionality, I would absolutely not
+// go about doing it this way: the semantics are just not very well
+// defined, and in any case you probably wanted to operate on trees,
+// not token streams.

+ *        processed
+ *      - CurrentCSSProperty: the name of the CSS property that is
+ *        currently being processed (if applicable)
+ *
+ * @warning This filter is called before scheme object validation occurs.
+ *          Make sure, if you require a specific scheme object, you
+ *          you check that it exists. This allows filters to convert

+
+## Overview
+
+A fast and simple streaming zip file downloader for PHP. Using this library will save you from having to write the Zip to disk. You can directly send it to the user, which is much faster. It can work with S3 buckets or any PSR7 Stream.
+
+Please see the [LICENSE](LICENSE) file for licensing and warranty information.
+
+## Installation
+
+Simply add a dependency on maennchen/zipstream-php to your project's composer.json file if you use Composer to manage the dependencies of your project. Use following command to add the package to your project's dependencies:
+
+```bash
+composer require maennchen/zipstream-php
+```
+
+## Usage and options
+
+Here's a simple example:
+
+```php
+// Autoload the dependencies
+require 'vendor/autoload.php';
+
+// enable output of HTTP headers
+$options = new ZipStream\Option\Archive();
+$options->setSendHttpHeaders(true);
+
+// create a new zipstream object
+$zip = new ZipStream\ZipStream('example.zip', $options);
+
+// create a file named 'hello.txt'
+$zip->addFile('hello.txt', 'This is the contents of hello.txt');
+
+// add a file named 'some_image.jpg' from a local file 'path/to/image.jpg'
+$zip->addFileFromPath('some_image.jpg', 'path/to/image.jpg');
+
+// add a file named 'goodbye.txt' from an open stream resource
+$fp = tmpfile();
+fwrite($fp, 'The quick brown fox jumped over the lazy dog.');
+rewind($fp);
+$zip->addFileFromStream('goodbye.txt', $fp);
+fclose($fp);
+
+// finish the zip stream
+$zip->finish();
+```
+
+You can also add comments, modify file timestamps, and customize (or
+disable) the HTTP headers. It is also possible to specify the storage method when adding files,
+the current default storage method is 'deflate' i.e files are stored with Compression mode 0x08.
+
+See the [Wiki](https://github.com/maennchen/ZipStream-PHP/wiki) for details.
+
+## Known issue
+
+The native Mac OS archive extraction tool might not open archives in some conditions. A workaround is to disable the Zip64 feature with the option `$opt->setEnableZip64(false)`. This limits the archive to 4 Gb and 64k files but will allow Mac OS users to open them without issue. See #116.
+
+The linux `unzip` utility might not handle properly unicode characters. It is recommended to extract with another tool like [7-zip](https://www.7-zip.org/). See #146.
+
+## Upgrade to version 2.0.0
+
+* Only the self opened streams will be closed (#139)
+If you were relying on ZipStream to close streams that the library didn't open,
+you'll need to close them yourself now.
+
+## Upgrade to version 1.0.0
+
+* All options parameters to all function have been moved from an `array` to structured option objects. See [the wiki](https://github.com/maennchen/ZipStream-PHP/wiki/Available-options) for examples.
+* The whole library has been refactored. The minimal PHP requirement has been raised to PHP 7.1.
+
+## Usage with Symfony and S3
+
+You can find example code on [the wiki](https://github.com/maennchen/ZipStream-PHP/wiki/Symfony-example).

+/**
+ * ZipStream
+ *
+ * Streamed, dynamically generated zip archives.
+ *
+ * Usage:
+ *
+ * Streaming zip archives is a simple, three-step process:
+ *
+ * 1.  Create the zip stream:
+ *
+ *     $zip = new ZipStream('example.zip');
+ *
+ * 2.  Add one or more files to the archive:
+ *
+ *      * add first file
+ *     $data = file_get_contents('some_file.gif');
+ *     $zip->addFile('some_file.gif', $data);
+ *
+ *      * add second file
+ *     $data = file_get_contents('some_file.gif');
+ *     $zip->addFile('another_file.png', $data);
+ *
+ * 3.  Finish the zip stream:
+ *
+ *     $zip->finish();
+ *
+ * You can also add an archive comment, add comments to individual files,
+ * and adjust the timestamp of files. See the API documentation for each
+ * method below for additional information.
+ *
+ * Example:
+ *
+ *   // create a new zip stream object
+ *   $zip = new ZipStream('some_files.zip');
+ *
+ *   // list of local files
+ *   $files = array('foo.txt', 'bar.jpg');
+ *
+ *   // read and add each file to the archive
+ *   foreach ($files as $path)
+ *     $zip->addFile($path, file_get_contents($path));
+ *
+ *   // write archive footer to stream
+ *   $zip->finish();

+     *
+     * The lower byte (rightmost one) indicates the version number of the
+     * software used to encode the file.  The value/10
+     * indicates the major version number, and the value
+     * mod 10 is the minor version number.
+     * Here we are using 6 for the OS, indicating OS/2 H.P.F.S.

+     * Large File Support:
+     *
+     * By default, the method addFileFromPath() will send send files
+     * larger than 20 megabytes along raw rather than attempting to
+     * compress them.  You can change both the maximum size and the
+     * compression behavior using the largeFile* options above, with the
+     * following caveats:
+     *
+     * * For "small" files (e.g. files smaller than largeFileSize), the
+     *   memory use can be up to twice that of the actual file.  In other
+     *   words, adding a 10 megabyte file to the archive could potentially
+     *   occupy 20 megabytes of memory.
+     *
+     * * Enabling compression on large files (e.g. files larger than
+     *   large_file_size) is extremely slow, because ZipStream has to pass
+     *   over the large file once to calculate header information, and then
+     *   again to compress and send the actual data.
+     *
+     * Examples:
+     *
+     *   // create a new zip file named 'foo.zip'
+     *   $zip = new ZipStream('foo.zip');
+     *
+     *   // create a new zip file named 'bar.zip' with a comment

+PHPComplex
+==========
+
+---
+
+PHP Class Library for working with Complex numbers
+
+[![Build Status](https://github.com/MarkBaker/PHPComplex/workflows/main/badge.svg)](https://github.com/MarkBaker/PHPComplex/actions)
+[![Total Downloads](https://img.shields.io/packagist/dt/markbaker/complex)](https://packagist.org/packages/markbaker/complex)
+[![Latest Stable Version](https://img.shields.io/github/v/release/MarkBaker/PHPComplex)](https://packagist.org/packages/markbaker/complex)
+[![License](https://img.shields.io/github/license/MarkBaker/PHPComplex)](https://packagist.org/packages/markbaker/complex)
+
+
+[![Complex Numbers](https://imgs.xkcd.com/comics/complex_numbers_2x.png)](https://xkcd.com/2028/)
+
+---
+
+The library currently provides the following operations:
+
+ - addition
+ - subtraction
+ - multiplication
+ - division
+    - division by
+    - division into
+
+together with functions for 
+
+ - theta (polar theta angle)
+ - rho (polar distance/radius)
+ - conjugate
+ * negative
+ - inverse (1 / complex)
+ - cos (cosine)
+ - acos (inverse cosine)
+ - cosh (hyperbolic cosine)
+ - acosh (inverse hyperbolic cosine)
+ - sin (sine)
+ - asin (inverse sine)
+ - sinh (hyperbolic sine)
+ - asinh (inverse hyperbolic sine)
+ - sec (secant)
+ - asec (inverse secant)
+ - sech (hyperbolic secant)
+ - asech (inverse hyperbolic secant)
+ - csc (cosecant)
+ - acsc (inverse cosecant)
+ - csch (hyperbolic secant)
+ - acsch (inverse hyperbolic secant)
+ - tan (tangent)
+ - atan (inverse tangent)
+ - tanh (hyperbolic tangent)
+ - atanh (inverse hyperbolic tangent)
+ - cot (cotangent)
+ - acot (inverse cotangent)
+ - coth (hyperbolic cotangent)
+ - acoth (inverse hyperbolic cotangent)
+ - sqrt (square root)
+ - exp (exponential)
+ - ln (natural log)
+ - log10 (base-10 log)
+ - log2 (base-2 log)
+ - pow (raised to the power of a real number)
+ 
+ 
+---
+
+# Installation
+
+```shell
+composer require markbaker/complex:^1.0
+```
+
+# Important BC Note
+
+If you've previously been using procedural calls to functions and operations using this library, then from version 3.0 you should use [MarkBaker/PHPComplexFunctions](https://github.com/MarkBaker/PHPComplexFunctions) instead (available on packagist as [markbaker/complex-functions](https://packagist.org/packages/markbaker/complex-functions)).
+
+You'll need to replace `markbaker/complex`in your `composer.json` file with the new library, but otherwise there should be no difference in the namespacing, or in the way that you have called the Complex functions in the past, so no actual code changes are required.
+
+```shell
+composer require markbaker/complex-functions:^3.0
+```
+
+You should not reference this library (`markbaker/complex`) in your `composer.json`, composer wil take care of that for you.
+
+# Usage
+
+To create a new complex object, you can provide either the real, imaginary and suffix parts as individual values, or as an array of values passed passed to the constructor; or a string representing the value. e.g
+
+```php
+$real = 1.23;
+$imaginary = -4.56;
+$suffix = 'i';
+
+$complexObject = new Complex\Complex($real, $imaginary, $suffix);
+```
+or as an array
+```php
+$real = 1.23;
+$imaginary = -4.56;
+$suffix = 'i';
+
+$arguments = [$real, $imaginary, $suffix];
+
+$complexObject = new Complex\Complex($arguments);
+```
+or as a string
+```php
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+```
+
+Complex objects are immutable: whenever you call a method or pass a complex value to a function that returns a complex value, a new Complex object will be returned, and the original will remain unchanged.
+This also allows you to chain multiple methods as you would for a fluent interface (as long as they are methods that will return a Complex result).
+
+## Performing Mathematical Operations
+
+To perform mathematical operations with Complex values, you can call the appropriate method against a complex value, passing other values as arguments
+
+```php
+$complexString1 = '1.23-4.56i';
+$complexString2 = '2.34+5.67i';
+
+$complexObject = new Complex\Complex($complexString1);
+echo $complexObject->add($complexString2);
+```
+
+or use the static Operation methods
+```php
+$complexString1 = '1.23-4.56i';
+$complexString2 = '2.34+5.67i';
+
+echo Complex\Operations::add($complexString1, $complexString2);
+```
+If you want to perform the same operation against multiple values (e.g. to add three or more complex numbers), then you can pass multiple arguments to any of the operations.
+
+You can pass these arguments as Complex objects, or as an array, or string that will parse to a complex object.
+
+## Using functions
+
+When calling any of the available functions for a complex value, you can either call the relevant method for the Complex object
+```php
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo $complexObject->sinh();
+```
+
+or use the static Functions methods
+```php
+$complexString = '1.23-4.56i';
+
+echo Complex\Functions::sinh($complexString);
+```
+As with operations, you can pass these arguments as Complex objects, or as an array or string that will parse to a complex object.
+
+
+In the case of the `pow()` function (the only implemented function that requires an additional argument) you need to pass both arguments when calling the function
+
+```php
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo Complex\Functions::pow($complexObject, 2);
+```
+or pass the additional argument when calling the method
+```php
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo $complexObject->pow(2);
+```

+
+# Installation
+
+```shell
+composer require markbaker/matrix:^3.0
+```
+
+# Important BC Note
+
+If you've previously been using procedural calls to functions and operations using this library, then from version 3.0 you should use [MarkBaker/PHPMatrixFunctions](https://github.com/MarkBaker/PHPMatrixFunctions) instead (available on packagist as [markbaker/matrix-functions](https://packagist.org/packages/markbaker/matrix-functions)).
+
+You'll need to replace `markbaker/matrix`in your `composer.json` file with the new library, but otherwise there should be no difference in the namespacing, or in the way that you have called the Matrix functions in the past, so no actual code changes are required.
+
+```shell
+composer require markbaker/matrix-functions:^1.0
+```
+
+You should not reference this library (`markbaker/matrix`) in your `composer.json`, composer wil take care of that for you.
+
+# Usage
+
+To create a new Matrix object, provide an array as the constructor argument
+
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+$matrix = new Matrix\Matrix($grid);
+```
+The `Builder` class provides helper methods for creating specific matrices, specifically an identity matrix of a specified size; or a matrix of a specified dimensions, with every cell containing a set value.
+```php
+$matrix = Matrix\Builder::createFilledMatrix(1, 5, 3);
+```
+Will create a matrix of 5 rows and 3 columns, filled with a `1` in every cell; while
+```php
+$matrix = Matrix\Builder::createIdentityMatrix(3);
+```
+will create a 3x3 identity matrix.
+
+
+Matrix objects are immutable: whenever you call a method or pass a grid to a function that returns a matrix value, a new Matrix object will be returned, and the original will remain unchanged. This also allows you to chain multiple methods as you would for a fluent interface (as long as they are methods that will return a Matrix result).
+
+## Performing Mathematical Operations
+
+To perform mathematical operations with Matrices, you can call the appropriate method against a matrix value, passing other values as arguments
+
+```php
+$matrix1 = new Matrix\Matrix([
+    [2, 7, 6],
+    [9, 5, 1],
+    [4, 3, 8],
+]);
+$matrix2 = new Matrix\Matrix([
+    [1, 2, 3],
+    [4, 5, 6],
+    [7, 8, 9],
+]);
+
+var_dump($matrix1->multiply($matrix2)->toArray());
+```
+or pass all values to the appropriate static method
+```php
+$matrix1 = new Matrix\Matrix([
+    [2, 7, 6],
+    [9, 5, 1],
+    [4, 3, 8],
+]);
+$matrix2 = new Matrix\Matrix([
+    [1, 2, 3],
+    [4, 5, 6],
+    [7, 8, 9],
+]);
+
+var_dump(Matrix\Operations::multiply($matrix1, $matrix2)->toArray());
+```
+You can pass in the arguments as Matrix objects, or as arrays.
+
+If you want to perform the same operation against multiple values (e.g. to add three or more matrices), then you can pass multiple arguments to any of the operations.
+
+## Using functions
+
+When calling any of the available functions for a matrix value, you can either call the relevant method for the Matrix object
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+$matrix = new Matrix\Matrix($grid);
+
+echo $matrix->trace();
+```
+or you can call the static method, passing the Matrix object or array as an argument 
+```php
+$grid = [

+## Decomposition
+
+The library also provides classes for matrix decomposition. You can access these using
+```php
+$grid = [
+    [1, 2],
+    [3, 4],
+];
+
+$matrix = new Matrix\Matrix($grid);
+
+$decomposition = new Matrix\Decomposition\QR($matrix);
+$Q = $decomposition->getQ();
+$R = $decomposition->getR();
+```
+
+or alternatively us the `Decomposition` factory, identifying which form of decomposition you want to use
+```php
+$grid = [
+    [1, 2],
+    [3, 4],
+];
+
+$matrix = new Matrix\Matrix($grid);
+
+$decomposition = Matrix\Decomposition\Decomposition::decomposition(Matrix\Decomposition\Decomposition::QR, $matrix);
+$Q = $decomposition->getQ();
+$R = $decomposition->getR();
+```

+# PHP Enum implementation inspired from SplEnum
+
+[![GitHub Actions][GA Image]][GA Link]
+[![Latest Stable Version](https://poser.pugx.org/myclabs/php-enum/version.png)](https://packagist.org/packages/myclabs/php-enum)
+[![Total Downloads](https://poser.pugx.org/myclabs/php-enum/downloads.png)](https://packagist.org/packages/myclabs/php-enum)
+[![Psalm Shepherd][Shepherd Image]][Shepherd Link]
+
+Maintenance for this project is [supported via Tidelift](https://tidelift.com/subscription/pkg/packagist-myclabs-php-enum?utm_source=packagist-myclabs-php-enum&utm_medium=referral&utm_campaign=readme).
+
+## Why?
+
+First, and mainly, `SplEnum` is not integrated to PHP, you have to install the extension separately.
+
+Using an enum instead of class constants provides the following advantages:
+
+- You can use an enum as a parameter type: `function setAction(Action $action) {`
+- You can use an enum as a return type: `function getAction() : Action {`
+- You can enrich the enum with methods (e.g. `format`, `parse`, …)
+- You can extend the enum to add new values (make your enum `final` to prevent it)
+- You can get a list of all the possible values (see below)
+
+This Enum class is not intended to replace class constants, but only to be used when it makes sense.
+
+## Installation
+
+```
+composer require myclabs/php-enum
+```
+
+## Declaration
+
+```php
+use MyCLabs\Enum\Enum;
+
+/**
+ * Action enum
+ */
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+```
+
+## Usage
+
+```php
+$action = Action::VIEW();
+
+// or with a dynamic key:
+$action = Action::$key();
+// or with a dynamic value:
+$action = Action::from($value);
+// or
+$action = new Action($value);
+```
+
+As you can see, static methods are automatically implemented to provide quick access to an enum value.
+
+One advantage over using class constants is to be able to use an enum as a parameter type:
+
+```php
+function setAction(Action $action) {
+    // ...
+}
+```
+
+## Documentation
+
+- `__construct()` The constructor checks that the value exist in the enum
+- `__toString()` You can `echo $myValue`, it will display the enum value (value of the constant)
+- `getValue()` Returns the current value of the enum
+- `getKey()` Returns the key of the current value on Enum
+- `equals()` Tests whether enum instances are equal (returns `true` if enum values are equal, `false` otherwise)
+
+Static methods:
+
+- `from()` Creates an Enum instance, checking that the value exist in the enum
+- `toArray()` method Returns all possible values as an array (constant name in key, constant value in value)
+- `keys()` Returns the names (keys) of all constants in the Enum class
+- `values()` Returns instances of the Enum class of all Enum constants (constant name in key, Enum instance in value)
+- `isValid()` Check if tested value is valid on enum set
+- `isValidKey()` Check if tested key is valid on enum set
+- `assertValidValue()` Assert the value is valid on enum set, throwing exception otherwise
+- `search()` Return key for searched value
+
+### Static methods
+
+```php
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+
+// Static method:
+$action = Action::VIEW();
+$action = Action::EDIT();
+```
+
+Static method helpers are implemented using [`__callStatic()`](http://www.php.net/manual/en/language.oop5.overloading.php#object.callstatic).
+
+If you care about IDE autocompletion, you can either implement the static methods yourself:
+
+```php
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+
+    /**
+     * @return Action
+     */
+    public static function VIEW() {
+        return new Action(self::VIEW);
+    }
+}
+```
+
+or you can use phpdoc (this is supported in PhpStorm for example):
+
+```php
+/**
+ * @method static Action VIEW()
+ * @method static Action EDIT()
+ */
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+```
+
+## Native enums and migration
+Native enum arrived to PHP in version 8.1: https://www.php.net/enumerations  
+If your project is running PHP 8.1+ or your library has it as a minimum requirement you should use it instead of this library.
+
+When migrating from `myclabs/php-enum`, the effort should be small if the usage was in the recommended way:
+- private constants
+- final classes
+- no method overridden
+
+Changes for migration:
+- Class definition should be changed from
+```php
+/**
+ * @method static Action VIEW()
+ * @method static Action EDIT()
+ */
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+```
+ to
+```php
+enum Action: string
+{
+    case VIEW = 'view';
+    case EDIT = 'edit';
+}
+```
+All places where the class was used as a type will continue to work.
+
+Usages and the change needed:

+GPL Cooperation Commitment
+Version 1.0
+
+Before filing or continuing to prosecute any legal proceeding or claim
+(other than a Defensive Action) arising from termination of a Covered
+License, we commit to extend to the person or entity ('you') accused
+of violating the Covered License the following provisions regarding
+cure and reinstatement, taken from GPL version 3. As used here, the
+term 'this License' refers to the specific Covered License being
+enforced.
+
+    However, if you cease all violation of this License, then your
+    license from a particular copyright holder is reinstated (a)
+    provisionally, unless and until the copyright holder explicitly
+    and finally terminates your license, and (b) permanently, if the
+    copyright holder fails to notify you of the violation by some
+    reasonable means prior to 60 days after the cessation.
+
+    Moreover, your license from a particular copyright holder is
+    reinstated permanently if the copyright holder notifies you of the
+    violation by some reasonable means, this is the first time you
+    have received notice of violation of this License (for any work)
+    from that copyright holder, and you cure the violation prior to 30
+    days after your receipt of the notice.
+
+We intend this Commitment to be irrevocable, and binding and
+enforceable against us and assignees of or successors to our
+copyrights.
+
+Definitions
+
+'Covered License' means the GNU General Public License, version 2
+(GPLv2), the GNU Lesser General Public License, version 2.1
+(LGPLv2.1), or the GNU Library General Public License, version 2

+                  GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+## Features
+- Probably the world's most popular code for sending email from PHP!
+- Used by many open-source projects: WordPress, Drupal, 1CRM, SugarCRM, Yii, Joomla! and many more
+- Integrated SMTP support – send without a local mail server
+- Send emails with multiple To, CC, BCC, and Reply-to addresses
+- Multipart/alternative emails for mail clients that do not read HTML email
+- Add attachments, including inline
+- Support for UTF-8 content and 8bit, base64, binary, and quoted-printable encodings
+- SMTP authentication with LOGIN, PLAIN, CRAM-MD5, and XOAUTH2 mechanisms over SMTPS and SMTP+STARTTLS transports
+- Validates email addresses automatically
+- Protects against header injection attacks
+- Error messages in over 50 languages!
+- DKIM and S/MIME signing support
+- Compatible with PHP 5.5 and later, including PHP 8.2
+- Namespaced to prevent name clashes
+- Much more!
+
+## Why you might need it
+Many PHP developers need to send email from their code. The only PHP function that supports this directly is [`mail()`](https://www.php.net/manual/en/function.mail.php). However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments.
+
+Formatting email correctly is surprisingly difficult. There are myriad overlapping (and conflicting) standards, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the `mail()` function directly is just plain wrong, if not unsafe!
+
+The PHP `mail()` function usually sends via a local mail server, typically fronted by a `sendmail` binary on Linux, BSD, and macOS platforms, however, Windows usually doesn't include a local mail server; PHPMailer's integrated SMTP client allows email sending on all platforms without needing a local mail server. Be aware though, that the `mail()` function should be avoided when possible; it's both faster and [safer](https://exploitbox.io/paper/Pwning-PHP-Mail-Function-For-Fun-And-RCE.html) to use SMTP to localhost.
+
+*Please* don't be tempted to do it yourself – if you don't use PHPMailer, there are many other excellent libraries that
+you should look at before rolling your own. Try [SwiftMailer](https://swiftmailer.symfony.com/)
+, [Laminas/Mail](https://docs.laminas.dev/laminas-mail/), [ZetaComponents](https://github.com/zetacomponents/Mail), etc.
+
+## License
+This software is distributed under the [LGPL 2.1](http://www.gnu.org/licenses/lgpl-2.1.html) license, along with the [GPL Cooperation Commitment](https://gplcc.github.io/gplcc/). Please read [LICENSE](https://github.com/PHPMailer/PHPMailer/blob/master/LICENSE) for information on the software availability and distribution.
+
+## Installation & loading
+PHPMailer is available on [Packagist](https://packagist.org/packages/phpmailer/phpmailer) (using semantic versioning), and installation via [Composer](https://getcomposer.org) is the recommended way to install PHPMailer. Just add this line to your `composer.json` file:
+
+```json
+"phpmailer/phpmailer": "^6.9.1"
+```
+
+or run
+
+```sh
+composer require phpmailer/phpmailer
+```
+
+Note that the `vendor` folder and the `vendor/autoload.php` script are generated by Composer; they are not part of PHPMailer.
+
+If you want to use XOAUTH2 authentication, you will also need to add a dependency on the `league/oauth2-client` and appropriate service adapters package in your `composer.json`, or take a look at
+by @decomplexity's [SendOauth2 wrapper](https://github.com/decomplexity/SendOauth2), especially if you're using Microsoft services.
+
+Alternatively, if you're not using Composer, you
+can [download PHPMailer as a zip file](https://github.com/PHPMailer/PHPMailer/archive/master.zip), (note that docs and examples are not included in the zip file), then copy the contents of the PHPMailer folder into one of the `include_path` directories specified in your PHP configuration and load each class file manually:
+
+```php
+<?php
+use PHPMailer\PHPMailer\PHPMailer;
+use PHPMailer\PHPMailer\Exception;
+
+require 'path/to/PHPMailer/src/Exception.php';
+require 'path/to/PHPMailer/src/PHPMailer.php';
+require 'path/to/PHPMailer/src/SMTP.php';
+```
+
+If you're not using the `SMTP` class explicitly (you're probably not), you don't need a `use` line for the SMTP class. Even if you're not using exceptions, you do still need to load the `Exception` class as it is used internally.
+
+## Legacy versions
+PHPMailer 5.2 (which is compatible with PHP 5.0 — 7.0) is no longer supported, even for security updates. You will find the latest version of 5.2 in the [5.2-stable branch](https://github.com/PHPMailer/PHPMailer/tree/5.2-stable). If you're using PHP 5.5 or later (which you should be), switch to the 6.x releases.
+
+### Upgrading from 5.2
+The biggest changes are that source files are now in the `src/` folder, and PHPMailer now declares the namespace `PHPMailer\PHPMailer`. This has several important effects – [read the upgrade guide](https://github.com/PHPMailer/PHPMailer/tree/master/UPGRADING.md) for more details.
+
+### Minimal installation
+While installing the entire package manually or with Composer is simple, convenient, and reliable, you may want to include only vital files in your project. At the very least you will need [src/PHPMailer.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/PHPMailer.php). If you're using SMTP, you'll need [src/SMTP.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/SMTP.php), and if you're using POP-before SMTP (*very* unlikely!), you'll need [src/POP3.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/POP3.php). You can skip the [language](https://github.com/PHPMailer/PHPMailer/tree/master/language/) folder if you're not showing errors to users and can make do with English-only errors. If you're using XOAUTH2 you will need [src/OAuth.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/OAuth.php) as well as the Composer dependencies for the services you wish to authenticate with. Really, it's much easier to use Composer!
+
+## A Simple Example
+
+```php
+<?php
+//Import PHPMailer classes into the global namespace
+//These must be at the top of your script, not inside a function
+use PHPMailer\PHPMailer\PHPMailer;
+use PHPMailer\PHPMailer\SMTP;
+use PHPMailer\PHPMailer\Exception;
+
+//Load Composer's autoloader
+require 'vendor/autoload.php';
+
+//Create an instance; passing `true` enables exceptions
+$mail = new PHPMailer(true);
+
+try {
+    //Server settings
+    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      //Enable verbose debug output
+    $mail->isSMTP();                                            //Send using SMTP
+    $mail->Host       = 'smtp.example.com';                     //Set the SMTP server to send through
+    $mail->SMTPAuth   = true;                                   //Enable SMTP authentication
+    $mail->Username   = 'user@example.com';                     //SMTP username
+    $mail->Password   = 'secret';                               //SMTP password
+    $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS;            //Enable implicit TLS encryption
+    $mail->Port       = 465;                                    //TCP port to connect to; use 587 if you have set `SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS`
+
+    //Recipients
+    $mail->setFrom('from@example.com', 'Mailer');
+    $mail->addAddress('joe@example.net', 'Joe User');     //Add a recipient
+    $mail->addAddress('ellen@example.com');               //Name is optional
+    $mail->addReplyTo('info@example.com', 'Information');
+    $mail->addCC('cc@example.com');
+    $mail->addBCC('bcc@example.com');
+
+    //Attachments
+    $mail->addAttachment('/var/tmp/file.tar.gz');         //Add attachments
+    $mail->addAttachment('/tmp/image.jpg', 'new.jpg');    //Optional name
+
+    //Content
+    $mail->isHTML(true);                                  //Set email format to HTML
+    $mail->Subject = 'Here is the subject';
+    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
+    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
+
+    $mail->send();
+    echo 'Message has been sent';
+} catch (Exception $e) {
+    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
+}
+```
+
+You'll find plenty to play with in the [examples](https://github.com/PHPMailer/PHPMailer/tree/master/examples) folder, which covers many common scenarios including sending through Gmail, building contact forms, sending to mailing lists, and more.
+
+If you are re-using the instance (e.g. when sending to a mailing list), you may need to clear the recipient list to avoid sending duplicate messages. See [the mailing list example](https://github.com/PHPMailer/PHPMailer/blob/master/examples/mailing_list.phps) for further guidance.
+
+That's it. You should now be ready to use PHPMailer!
+
+## Localization
+PHPMailer defaults to English, but in the [language](https://github.com/PHPMailer/PHPMailer/tree/master/language/) folder, you'll find many translations for PHPMailer error messages that you may encounter. Their filenames contain [ISO 639-1](http://en.wikipedia.org/wiki/ISO_639-1) language code for the translations, for example `fr` for French. To specify a language, you need to tell PHPMailer which one to use, like this:
+
+```php
+//To load the French version
+$mail->setLanguage('fr', '/optional/path/to/language/directory/');
+```
+
+We welcome corrections and new languages – if you're looking for corrections, run the [Language/TranslationCompletenessTest.php](https://github.com/PHPMailer/PHPMailer/blob/master/test/Language/TranslationCompletenessTest.php) script in the tests folder and it will show any missing translations.
+
+## Documentation
+Start reading at the [GitHub wiki](https://github.com/PHPMailer/PHPMailer/wiki). If you're having trouble, head for [the troubleshooting guide](https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting) as it's frequently updated.
+
+Examples of how to use PHPMailer for common scenarios can be found in the [examples](https://github.com/PHPMailer/PHPMailer/tree/master/examples) folder. If you're looking for a good starting point, we recommend you start with [the Gmail example](https://github.com/PHPMailer/PHPMailer/tree/master/examples/gmail.phps).
+
+To reduce PHPMailer's deployed code footprint, examples are not included if you load PHPMailer via Composer or via [GitHub's zip file download](https://github.com/PHPMailer/PHPMailer/archive/master.zip), so you'll need to either clone the git repository or use the above links to get to the examples directly.
+
+Complete generated API documentation is [available online](https://phpmailer.github.io/PHPMailer/).
+
+You can generate complete API-level documentation by running `phpdoc` in the top-level folder, and documentation will appear in the `docs` folder, though you'll need to have [PHPDocumentor](http://www.phpdoc.org) installed. You may find [the unit tests](https://github.com/PHPMailer/PHPMailer/blob/master/test/PHPMailerTest.php) a good reference for how to do various operations such as encryption.
+
+If the documentation doesn't cover what you need, search the [many questions on Stack Overflow](http://stackoverflow.com/questions/tagged/phpmailer), and before you ask a question about "SMTP Error: Could not connect to SMTP host.", [read the troubleshooting guide](https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting).
+
+## Tests
+[PHPMailer tests](https://github.com/PHPMailer/PHPMailer/tree/master/test/) use PHPUnit 9, with [a polyfill](https://github.com/Yoast/PHPUnit-Polyfills) to let 9-style tests run on older PHPUnit and PHP versions.
+

+## History
+- PHPMailer was originally written in 2001 by Brent R. Matzelle as a [SourceForge project](http://sourceforge.net/projects/phpmailer/).
+- [Marcus Bointon](https://github.com/Synchro) (`coolbru` on SF) and Andy Prevost (`codeworxtech`) took over the project in 2004.
+- Became an Apache incubator project on Google Code in 2010, managed by Jim Jagielski.
+- Marcus created [his fork on GitHub](https://github.com/Synchro/PHPMailer) in 2008.
+- Jim and Marcus decide to join forces and use GitHub as the canonical and official repo for PHPMailer in 2013.
+- PHPMailer moves to [the PHPMailer organisation](https://github.com/PHPMailer) on GitHub in 2013.
+
+### What's changed since moving from SourceForge?
+- Official successor to the SourceForge and Google Code projects.
+- Test suite.
+- Continuous integration with GitHub Actions.
+- Composer support.
+- Public development.
+- Additional languages and language strings.
+- CRAM-MD5 authentication support.
+- Preserves full repo history of authors, commits, and branches from the original SourceForge project.

+# Security notices relating to PHPMailer
+
+Please disclose any security issues or vulnerabilities found through [Tidelift's coordinated disclosure system](https://tidelift.com/security) or to the maintainers privately.
+
+PHPMailer 6.4.1 and earlier contain a vulnerability that can result in untrusted code being called (if such code is injected into the host project's scope by other means). If the `$patternselect` parameter to `validateAddress()` is set to `'php'` (the default, defined by `PHPMailer::$validator`), and the global namespace contains a function called `php`, it will be called in preference to the built-in validator of the same name. Mitigated in PHPMailer 6.5.0 by denying the use of simple strings as validator function names. Recorded as [CVE-2021-3603](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-3603). Reported by [Vikrant Singh Chauhan](mailto:vi@hackberry.xyz) via [huntr.dev](https://www.huntr.dev/).
+
+PHPMailer versions 6.4.1 and earlier contain a possible remote code execution vulnerability through the `$lang_path` parameter of the `setLanguage()` method. If the `$lang_path` parameter is passed unfiltered from user input, it can be set to [a UNC path](https://docs.microsoft.com/en-us/dotnet/standard/io/file-path-formats#unc-paths), and if an attacker is also able to persuade the server to load a file from that UNC path, a script file under their control may be executed. This vulnerability only applies to systems that resolve UNC paths, typically only Microsoft Windows.
+PHPMailer 6.5.0 mitigates this by no longer treating translation files as PHP code, but by parsing their text content directly. This approach avoids the possibility of executing unknown code while retaining backward compatibility. This isn't ideal, so the current translation format is deprecated and will be replaced in the next major release. Recorded as [CVE-2021-34551](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-34551). Reported by [Jilin Diting Information Technology Co., Ltd](https://listensec.com) via Tidelift.
+
+PHPMailer versions between 6.1.8 and 6.4.0 contain a regression of the earlier CVE-2018-19296 object injection vulnerability as a result of [a fix for Windows UNC paths in 6.1.8](https://github.com/PHPMailer/PHPMailer/commit/e2e07a355ee8ff36aba21d0242c5950c56e4c6f9). Recorded as [CVE-2020-36326](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-36326). Reported by Fariskhi Vidyan via Tidelift. 6.4.1 fixes this issue, and also enforces stricter checks for URL schemes in local path contexts.
+
+PHPMailer versions 6.1.5 and earlier contain an output escaping bug that occurs in `Content-Type` and `Content-Disposition` when filenames passed into `addAttachment` and other methods that accept attachment names contain double quote characters, in contravention of RFC822 3.4.1. No specific vulnerability has been found relating to this, but it could allow file attachments to bypass attachment filters that are based on matching filename extensions. Recorded as [CVE-2020-13625](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-13625). Reported by Elar Lang of Clarified Security.
+
+PHPMailer versions prior to 6.0.6 and 5.2.27 are vulnerable to an object injection attack by passing `phar://` paths into `addAttachment()` and other functions that may receive unfiltered local paths, possibly leading to RCE. Recorded as [CVE-2018-19296](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2018-19296). See [this article](https://knasmueller.net/5-answers-about-php-phar-exploitation) for more info on this type of vulnerability. Mitigated by blocking the use of paths containing URL-protocol style prefixes such as `phar://`. Reported by Sehun Oh of cyberone.kr.
+
+PHPMailer versions prior to 5.2.24 (released July 26th 2017) have an XSS vulnerability in one of the code examples, [CVE-2017-11503](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-11503). The `code_generator.phps` example did not filter user input prior to output. This file is distributed with a `.phps` extension, so it it not normally executable unless it is explicitly renamed, and the file is not included when PHPMailer is loaded through composer, so it is safe by default. There was also an undisclosed potential XSS vulnerability in the default exception handler (unused by default). Patches for both issues kindly provided by Patrick Monnerat of the Fedora Project.
+
+PHPMailer versions prior to 5.2.22 (released January 9th 2017) have a local file disclosure vulnerability, [CVE-2017-5223](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-5223). If content passed into `msgHTML()` is sourced from unfiltered user input, relative paths can map to absolute local file paths and added as attachments. Also note that `addAttachment` (just like `file_get_contents`, `passthru`, `unlink`, etc) should not be passed user-sourced params either! Reported by Yongxiang Li of Asiasecurity.
+
+PHPMailer versions prior to 5.2.20 (released December 28th 2016) are vulnerable to [CVE-2016-10045](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-10045) a remote code execution vulnerability, responsibly reported by [Dawid Golunski](https://legalhackers.com/advisories/PHPMailer-Exploit-Remote-Code-Exec-CVE-2016-10045-Vuln-Patch-Bypass.html), and patched by Paul Buonopane (@Zenexer).
+
+PHPMailer versions prior to 5.2.18 (released December 2016) are vulnerable to [CVE-2016-10033](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-10033) a remote code execution vulnerability, responsibly reported by [Dawid Golunski](http://legalhackers.com/advisories/PHPMailer-Exploit-Remote-Code-Exec-CVE-2016-10033-Vuln.html).
+
+PHPMailer versions prior to 5.2.14 (released November 2015) are vulnerable to [CVE-2015-8476](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-8476) an SMTP CRLF injection bug permitting arbitrary message sending.
+
+PHPMailer versions prior to 5.2.10 (released May 2015) are vulnerable to [CVE-2008-5619](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2008-5619), a remote code execution vulnerability in the bundled html2text library. This file was removed in 5.2.10, so if you are using a version prior to that and make use of the html2text function, it's vitally important that you upgrade and remove this file.
+
+PHPMailer versions prior to 2.0.7 and 2.2.1 are vulnerable to [CVE-2012-0796](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-0796), an email header injection attack.
+
+Joomla 1.6.0 uses PHPMailer in an unsafe way, allowing it to reveal local file paths, reported in [CVE-2011-3747](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2011-3747).
+
+PHPMailer didn't sanitise the `$lang_path` parameter in `SetLanguage`. This wasn't a problem in itself, but some apps (PHPClassifieds, ATutor) also failed to sanitise user-provided parameters passed to it, permitting semi-arbitrary local file inclusion, reported in [CVE-2010-4914](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2010-4914), [CVE-2007-2021](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2007-2021) and [CVE-2006-5734](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2006-5734).
+
+PHPMailer 1.7.2 and earlier contained a possible DDoS vulnerability reported in [CVE-2005-1807](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2005-1807).
+
+PHPMailer 1.7 and earlier (June 2003) have a possible vulnerability in the `SendmailSend` method where shell commands may not be sanitised. Reported in [CVE-2007-3215](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2007-3215).

+/**
+ * PHPMailer POP-Before-SMTP Authentication Class.
+ * Specifically for PHPMailer to use for RFC1939 POP-before-SMTP authentication.
+ * 1) This class does not support APOP authentication.
+ * 2) Opening and closing lots of POP3 connections can be quite slow. If you need
+ *   to send a batch of emails then just perform the authentication once at the start,
+ *   and then loop through your mail sending script. Providing this process doesn't
+ *   take longer than the verification period lasts on your POP3 server, you should be fine.
+ * 3) This is really ancient technology; you should only need to use it to talk to very old systems.
+ * 4) This POP3 class is deliberately lightweight and incomplete, implementing just
+ *   enough to do authentication.
+ *   If you want a more complete class there are other POP3 classes for PHP available.

+
+## 1.23.0 - 2022-04-24
+
+### Added
+
+- Ods Writer support for Freeze Pane [Issue #2013](https://github.com/PHPOffice/PhpSpreadsheet/issues/2013) [PR #2755](https://github.com/PHPOffice/PhpSpreadsheet/pull/2755)
+- Ods Writer support for setting column width/row height (including the use of AutoSize) [Issue #2346](https://github.com/PHPOffice/PhpSpreadsheet/issues/2346) [PR #2753](https://github.com/PHPOffice/PhpSpreadsheet/pull/2753)
+- Introduced CellAddress, CellRange, RowRange and ColumnRange value objects that can be used as an alternative to a string value (e.g. `'C5'`, `'B2:D4'`, `'2:2'` or `'B:C'`) in appropriate contexts.
+- Implementation of the FILTER(), SORT(), SORTBY() and UNIQUE() Lookup/Reference (array) functions.
+- Implementation of the ISREF() Information function.
+- Added support for reading "formatted" numeric values from Csv files; although default behaviour of reading these values as strings is preserved.
+
+  (i.e a value of "12,345.67" can be read as numeric `12345.67`, not simply as a string `"12,345.67"`, if the `castFormattedNumberToNumeric()` setting is enabled.
+
+  This functionality is locale-aware, using the server's locale settings to identify the thousands and decimal separators.
+
+- Support for two cell anchor drawing of images. [#2532](https://github.com/PHPOffice/PhpSpreadsheet/pull/2532) [#2674](https://github.com/PHPOffice/PhpSpreadsheet/pull/2674)
+- Limited support for Xls Reader to handle Conditional Formatting:
+
+  Ranges and Rules are read, but style is currently limited to font size, weight and color; and to fill style and color.
+
+- Add ability to suppress Mac line ending check for CSV [#2623](https://github.com/PHPOffice/PhpSpreadsheet/pull/2623)
+- Initial support for creating and writing Tables (Xlsx Writer only) [PR #2671](https://github.com/PHPOffice/PhpSpreadsheet/pull/2671)
+
+  See `/samples/Table` for examples of use.
+
+  Note that PreCalculateFormulas needs to be disabled when saving spreadsheets containing tables with formulae (totals or column formulae).
+
+### Changed
+
+- Gnumeric Reader now loads number formatting for cells.
+- Gnumeric Reader now correctly identifies selected worksheet and selected cells in a worksheet.
+- Some Refactoring of the Ods Reader, moving all formula and address translation from Ods to Excel into a separate class to eliminate code duplication and ensure consistency.
+- Make Boolean Conversion in Csv Reader locale-aware when using the String Value Binder.
+
+  This is determined by the Calculation Engine locale setting.
+
+  (i.e. `"Vrai"` wil be converted to a boolean `true` if the Locale is set to `fr`.)
+- Allow `psr/simple-cache` 2.x
+
+### Deprecated
+
+- All Excel Function implementations in `Calculation\Functions` (including the Error functions) have been moved to dedicated classes for groups of related functions. See the docblocks against all the deprecated methods for details of the new methods to call instead. At some point, these old classes will be deleted.
+- Worksheet methods that reference cells "byColumnandRow". All such methods have an equivalent that references the cell by its address (e.g. '`E3'` rather than `5, 3`).
+
+  These functions now accept either a cell address string (`'E3')` or an array with columnId and rowId (`[5, 3]`) or a new `CellAddress` object as their `cellAddress`/`coordinate` argument.
+  This includes the methods:
+  - `setCellValueByColumnAndRow()` use the equivalent `setCellValue()`
+  - `setCellValueExplicitByColumnAndRow()` use the equivalent `setCellValueExplicit()`
+  - `getCellByColumnAndRow()` use the equivalent `getCell()`
+  - `cellExistsByColumnAndRow()` use the equivalent `cellExists()`
+  - `getStyleByColumnAndRow()` use the equivalent `getStyle()`
+  - `setBreakByColumnAndRow()` use the equivalent `setBreak()`
+  - `mergeCellsByColumnAndRow()` use the equivalent `mergeCells()`
+  - `unmergeCellsByColumnAndRow()` use the equivalent `unmergeCells()`
+  - `protectCellsByColumnAndRow()` use the equivalent `protectCells()`
+  - `unprotectCellsByColumnAndRow()` use the equivalent `unprotectCells()`
+  - `setAutoFilterByColumnAndRow()` use the equivalent `setAutoFilter()`
+  - `freezePaneByColumnAndRow()` use the equivalent `freezePane()`
+  - `getCommentByColumnAndRow()` use the equivalent `getComment()`
+  - `setSelectedCellByColumnAndRow()` use the equivalent `setSelectedCells()`
+
+  This change provides more consistency in the methods (not every "by cell address" method has an equivalent "byColumnAndRow" method);
+  and the "by cell address" methods often provide more flexibility, such as allowing a range of cells, or referencing them by passing the defined name of a named range as the argument.
+
+### Removed
+
+- Nothing
+
+### Fixed
+
+- Make allowance for the AutoFilter dropdown icon in the first row of an Autofilter range when using Autosize columns. [Issue #2413](https://github.com/PHPOffice/PhpSpreadsheet/issues/2413) [PR #2754](https://github.com/PHPOffice/PhpSpreadsheet/pull/2754)
+- Support for "chained" ranges (e.g. `A5:C10:C20:F1`) in the Calculation Engine; and also support for using named ranges with the Range operator (e.g. `NamedRange1:NamedRange2`) [Issue #2730](https://github.com/PHPOffice/PhpSpreadsheet/issues/2730) [PR #2746](https://github.com/PHPOffice/PhpSpreadsheet/pull/2746)
+- Update Conditional Formatting ranges and rule conditions when inserting/deleting rows/columns [Issue #2678](https://github.com/PHPOffice/PhpSpreadsheet/issues/2678) [PR #2689](https://github.com/PHPOffice/PhpSpreadsheet/pull/2689)
+- Allow `INDIRECT()` to accept row/column ranges as well as cell ranges [PR #2687](https://github.com/PHPOffice/PhpSpreadsheet/pull/2687)
+- Fix bug when deleting cells with hyperlinks, where the hyperlink was then being "inherited" by whatever cell moved to that cell address.
+- Fix bug in Conditional Formatting in the Xls Writer that resulted in a broken file when there were multiple conditional ranges in a worksheet.
+- Fix Conditional Formatting in the Xls Writer to work with rules that contain string literals, cell references and formulae.
+- Fix for setting Active Sheet to the first loaded worksheet when bookViews element isn't defined [Issue #2666](https://github.com/PHPOffice/PhpSpreadsheet/issues/2666) [PR #2669](https://github.com/PHPOffice/PhpSpreadsheet/pull/2669)
+- Fixed behaviour of XLSX font style vertical align settings [PR #2619](https://github.com/PHPOffice/PhpSpreadsheet/pull/2619)
+- Resolved formula translations to handle separators (row and column) for array functions as well as for function argument separators; and cleanly handle nesting levels.
+
+  Note that this method is used when translating Excel functions between `en_us` and other locale languages, as well as when converting formulae between different spreadsheet formats (e.g. Ods to Excel).
+
+  Nor is this a perfect solution, as there may still be issues when function calls have array arguments that themselves contain function calls; but it's still better than the current logic.
+- Fix for escaping double quotes within a formula [Issue #1971](https://github.com/PHPOffice/PhpSpreadsheet/issues/1971) [PR #2651](https://github.com/PHPOffice/PhpSpreadsheet/pull/2651)

+- Handle booleans in conditional styles properly [PR #2654](https://github.com/PHPOffice/PhpSpreadsheet/pull/2654)
+- Fix for reading files in the root directory of a ZipFile, which should not be prefixed by relative paths ("./") as dirname($filename) does by default. 
+- Fix invalid style of cells in empty columns with columnDimensions and rows with rowDimensions in added external sheet. [PR #2739](https://github.com/PHPOffice/PhpSpreadsheet/pull/2739)

+- Support for the Excel365 Math/Trig RANDARRAY() function [PR #2540](https://github.com/PHPOffice/PhpSpreadsheet/pull/2540) 
+
+  Note that the Spill Operator is not yet supported in the Calculation Engine; but this can still be useful for defining array constants.
+- Improved support for Conditional Formatting Rules [PR #2491](https://github.com/PHPOffice/PhpSpreadsheet/pull/2491)
+  - Provide support for a wider range of Conditional Formatting Rules for Xlsx Reader/Writer:
+    - Cells Containing (cellIs)
+    - Specific Text (containing, notContaining, beginsWith, endsWith)
+    - Dates Occurring (all supported timePeriods)
+    - Blanks/NoBlanks
+    - Errors/NoErrors
+    - Duplicates/Unique
+    - Expression
+  - Provision of CF Wizards (for all the above listed rule types) to help create/modify CF Rules without having to manage all the combinations of types/operators, and the complexities of formula expressions, or the text/timePeriod attributes.
+
+    See [documentation](https://phpspreadsheet.readthedocs.io/en/latest/topics/conditional-formatting/) for details 
+
+  - Full support of the above CF Rules for the Xlsx Reader and Writer; even when the file being loaded has CF rules listed in the `<extLst><ext><ConditionalFormattings>` element for the worksheet rather than the `<ConditionalFormatting>` element.

+- Calling many of the Excel formula functions directly rather than through the Calculation Engine.
+
+  The logic for these Functions is now being moved out of the categorised `Database`, `DateTime`, `Engineering`, `Financial`, `Logical`, `LookupRef`, `MathTrig`, `Statistical`, `TextData` and `Web` classes into small, dedicated classes for individual functions or related groups of functions.
+
+  This makes the logic in these classes easier to maintain; and will reduce the memory footprint required to execute formulae when calling these functions.

+
+### Added
+
+- Implemented Page Order for Xlsx and Xls Readers, and provided Page Settings (Orientation, Scale, Horizontal/Vertical Centering, Page Order, Margins) support for Ods, Gnumeric and Xls Readers [#1559](https://github.com/PHPOffice/PhpSpreadsheet/pull/1559)
+- Implementation of the Excel `LOGNORM.DIST()`, `NORM.S.DIST()`, `GAMMA()` and `GAUSS()` functions. [#1588](https://github.com/PHPOffice/PhpSpreadsheet/pull/1588)
+- Named formula implementation, and improved handling of Defined Names generally [#1535](https://github.com/PHPOffice/PhpSpreadsheet/pull/1535)
+  - Defined Names are now case-insensitive
+  - Distinction between named ranges and named formulae
+  - Correct handling of union and intersection operators in named ranges
+  - Correct evaluation of named range operators in calculations
+  - fix resolution of relative named range values in the calculation engine; previously all named range values had been treated as absolute.
+  - Calculation support for named formulae
+  - Support for nested ranges and formulae (named ranges and formulae that reference other named ranges/formulae) in calculations
+  - Introduction of a helper to convert address formats between R1C1 and A1 (and the reverse)
+  - Proper support for both named ranges and named formulae in all appropriate Readers
+    - **Xlsx** (Previously only simple named ranges were supported)
+    - **Xls** (Previously only simple named ranges were supported)
+    - **Gnumeric** (Previously neither named ranges nor formulae were supported)
+    - **Ods** (Previously neither named ranges nor formulae were supported)
+    - **Xml** (Previously neither named ranges nor formulae were supported)
+  - Proper support for named ranges and named formulae in all appropriate Writers

+
+### Changed
+
+- Improve Coverage for ODS Reader [#1545](https://github.com/phpoffice/phpspreadsheet/pull/1545)
+- Named formula implementation, and improved handling of Defined Names generally [#1535](https://github.com/PHPOffice/PhpSpreadsheet/pull/1535)
+- fix resolution of relative named range values in the calculation engine; previously all named range values had been treated as absolute.
+- Drop $this->spreadSheet null check from Xlsx Writer [#1646](https://github.com/phpoffice/phpspreadsheet/pull/1646)
+- Improving Coverage for Excel2003 XML Reader [#1557](https://github.com/phpoffice/phpspreadsheet/pull/1557)
+
+### Deprecated
+
+- **IMPORTANT NOTE:** This Introduces a **BC break** in the handling of named ranges. Previously, a named range cell reference of `B2` would be treated identically to a named range cell reference of `$B2` or `B$2` or `$B$2` because the calculation engine treated then all as absolute references. These changes "fix" that, so the calculation engine now handles relative references in named ranges correctly.
+  This change that resolves previously incorrect behaviour in the calculation may affect users who have dynamically defined named ranges using relative references when they should have used absolute references.

+
+## 1.8.0 - 2019-07-01
+
+### Security Fix (CVE-2019-12331)
+
+- Detect double-encoded xml in the Security scanner, and reject as suspicious.
+- This change also broadens the scope of the `libxml_disable_entity_loader` setting when reading XML-based formats, so that it is enabled while the xml is being parsed and not simply while it is loaded.
+  On some versions of PHP, this can cause problems because it is not thread-safe, and can affect other PHP scripts running on the same server. This flag is set to true when instantiating a loader, and back to its original setting when the Reader is no longer in scope, or manually unset.
+- Provide a check to identify whether libxml_disable_entity_loader is thread-safe or not.
+
+  `XmlScanner::threadSafeLibxmlDisableEntityLoaderAvailability()`
+- Provide an option to disable the libxml_disable_entity_loader call through settings. This is not recommended as it reduces the security of the XML-based readers, and should only be used if you understand the consequences and have no other choice.
+
+### Added

+# Want to contribute?
+
+If you would like to contribute, here are some notes and guidelines:
+
+ - All new development happens on feature/fix branches, and are then merged to the `master` branch once stable; so the `master` branch is always the most up-to-date, working code
+ - Tagged releases are made from the `master` branch
+ - If you are going to be submitting a pull request, please fork from `master`, and submit your pull request back as a fix/feature branch referencing the GitHub issue number
+ - Code style might be automatically fixed by `composer fix`
+ - All code changes must be validated by `composer check`
+ - [Helpful article about forking](https://help.github.com/articles/fork-a-repo/ "Forking a GitHub repository")
+ - [Helpful article about pull requests](https://help.github.com/articles/using-pull-requests/ "Pull Requests")
+
+## How to release
+
+1. Complete CHANGELOG.md and commit
+2. Create an annotated tag
+    1. `git tag -a 1.2.3`
+    2. Tag subject must be the version number, eg: `1.2.3`
+    3. Tag body must be a copy-paste of the changelog entries
+3. Push tag with `git push --tags`, GitHub Actions will create a GitHub release automatically

+
+PhpSpreadsheet is a library written in pure PHP and offers a set of classes that
+allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc.
+
+## PHP version support
+
+LTS: Support for PHP versions will only be maintained for a period of six months beyond the
+[end of life of that PHP version](https://www.php.net/eol.php).
+
+Currently the required PHP minimum version is PHP __7.3__.
+
+See the `composer.json` for other requirements.
+
+## Installation
+
+Use [composer](https://getcomposer.org) to install PhpSpreadsheet into your project:
+
+```sh
+composer require phpoffice/phpspreadsheet
+```
+
+If you are building your installation on a development machine that is on a different PHP version to the server where it will be deployed, or if your PHP CLI version is not the same as your run-time such as `php-fpm` or Apache's `mod_php`, then you might want to add the following to your `composer.json` before installing:
+```json
+{
+    "require": {
+        "phpoffice/phpspreadsheet": "^1.23"
+    },
+    "config": {
+        "platform": {
+            "php": "7.3"
+        }
+    }
+}
+```
+and then run
+```sh
+composer install
+```
+to ensure that the correct dependencies are retrieved to match your deployment environment.
+
+See [CLI vs Application run-time](https://php.watch/articles/composer-platform-check) for more details.
+
+### Additional Installation Options
+
+If you want to write to PDF, or to include Charts when you write to HTML or PDF, then you will need to install additional libraries:

+For PDF Generation, you can install any of the following, and then configure PhpSpreadsheet to indicate which library you are going to use:
+ - mpdf/mpdf
+ - dompdf/dompdf
+ - tecnickcom/tcpdf
+
+and configure PhpSpreadsheet using:
+
+```php
+// Dompdf, Mpdf or Tcpdf (as appropriate)
+$className = \PhpOffice\PhpSpreadsheet\Writer\Pdf\Dompdf::class;
+IOFactory::registerWriter('Pdf', $className);
+```
+or the appropriate PDF Writer wrapper for the library that you have chosen to install.
+
+#### Chart Export
+
+For Chart export, we support following packages, which you will also need to install yourself using `composer require`
+ - [jpgraph/jpgraph](https://packagist.org/packages/jpgraph/jpgraph) (this package was abandoned at version 4.0. 
+   You can manually download the latest version that supports PHP 8 and above from [jpgraph.net](https://jpgraph.net/))
+ - [mitoteam/jpgraph](https://packagist.org/packages/mitoteam/jpgraph) (fork with php 8.1 support)
+
+and then configure PhpSpreadsheet using:
+```php
+Settings::setChartRenderer(\PhpOffice\PhpSpreadsheet\Chart\Renderer\JpGraph::class); // to use jpgraph/jpgraph
+//or
+Settings::setChartRenderer(\PhpOffice\PhpSpreadsheet\Chart\Renderer\MtJpGraphRenderer::class); // to use mitoteam/jpgraph
+```
+
+One or the other of these libraries is necessary if you want to generate HTML or PDF files that include charts.
+
+## Documentation
+
+Read more about it, including install instructions, in the [official documentation](https://phpspreadsheet.readthedocs.io). Or check out the [API documentation](https://phpoffice.github.io/PhpSpreadsheet).
+
+Please ask your support questions on [StackOverflow](https://stackoverflow.com/questions/tagged/phpspreadsheet), or have a quick chat on [Gitter](https://gitter.im/PHPOffice/PhpSpreadsheet).
+
+## PHPExcel vs PhpSpreadsheet ?
+
+PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
+
+Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet `master` branch.
+
+Do you need to migrate? There is [an automated tool](/docs/topics/migration-from-PHPExcel.md) for that.

+     * Excel Function:
+     *        DATE(year,month,day)
+     *
+     * PhpSpreadsheet is a lot more forgiving than MS Excel when passing non numeric values to this function.
+     * A Month name or abbreviation (English only at this point) such as 'January' or 'Jan' will still be accepted,
+     *     as will a day value with a suffix (e.g. '21st' rather than simply 21); again only English language.
+     *
+     * @param array|int $year The value of the year argument can include one to four digits.
+     *                                Excel interprets the year argument according to the configured
+     *                                date system: 1900 or 1904.
+     *                                If year is between 0 (zero) and 1899 (inclusive), Excel adds that
+     *                                value to 1900 to calculate the year. For example, DATE(108,1,2)
+     *                                returns January 2, 2008 (1900+108).
+     *                                If year is between 1900 and 9999 (inclusive), Excel uses that
+     *                                value as the year. For example, DATE(2008,1,2) returns January 2,
+     *                                2008.
+     *                                If year is less than 0 or is 10000 or greater, Excel returns the
+     *                                #NUM! error value.
+     * @param array|int $month A positive or negative integer representing the month of the year
+     *                                from 1 to 12 (January to December).
+     *                                If month is greater than 12, month adds that number of months to
+     *                                the first month in the year specified. For example, DATE(2008,14,2)
+     *                                returns the serial number representing February 2, 2009.
+     *                                If month is less than 1, month subtracts the magnitude of that
+     *                                number of months, plus 1, from the first month in the year
+     *                                specified. For example, DATE(2008,-3,2) returns the serial number
+     *                                representing September 2, 2007.
+     * @param array|int $day A positive or negative integer representing the day of the month
+     *                                from 1 to 31.
+     *                                If day is greater than the number of days in the month specified,
+     *                                day adds that number of days to the first day in the month. For

+     * This routine calculates the LOG(GAMMA) function for a positive real argument X.
+     * Computation is based on an algorithm outlined in references 1 and 2.
+     * The program uses rational functions that theoretically approximate LOG(GAMMA)
+     * to at least 18 significant decimal digits. The approximation for X > 12 is from
+     * reference 3, while approximations for X < 12.0 are similar to those in reference
+     * 1, but are unpublished. The accuracy achieved depends on the arithmetic system,
+     * the compiler, the intrinsic functions, and proper selection of the
+     * machine-dependent constants.

+     * <p>
+     * Error returns: <br />
+     * The program returns the value XINF for X .LE. 0.0 or when overflow would occur.

+// Adapted from Excel_Spreadsheet_Reader developed by users bizon153,
+// trex005, and mmp11 (SourceForge.net)
+// https://sourceforge.net/projects/phpexcelreader/
+// Primary changes made by canyoncasa (dvc) for ParseXL 1.00 ...
+//     Modelled moreso after Perl Excel Parse/Write modules
+//     Added Parse_Excel_Spreadsheet object
+//         Reads a whole worksheet or tab as row,column array or as
+//         associated hash of indexed rows and named column fields
+//     Added variables for worksheet (tab) indexes and names
+//     Added an object call for loading individual woorksheets
+//     Changed default indexing defaults to 0 based arrays
+//     Fixed date/time and percent formats
+//     Includes patches found at SourceForge...
+//         unicode patch by nobody
+//         unpack("d") machine depedency patch by matchy
+//         boundsheet utf16 patch by bjaenichen
+//     Renamed functions for shorter names
+//     General code cleanup and rigor, including <80 column width
+//     Included a testcase Excel file and PHP example calls
+//     Code works for PHP 5.x
+
+// Primary changes made by canyoncasa (dvc) for ParseXL 1.10 ...

+//     Decoding of formula conditions, results, and tokens.
+//     Support for user-defined named cells added as an array "namedcells"
+//         Patch code for user-defined named cells supports single cells only.

+ *    For an m-by-n matrix A with m >= n, the LU decomposition is an m-by-n
+ *    unit lower triangular matrix L, an n-by-n upper triangular matrix U,
+ *    and a permutation vector piv of length m so that A(piv,:) = L*U.
+ *    If m < n, then L is m-by-m and U is m-by-n.
+ *
+ *    The LU decompostion with pivoting always exists, even if the matrix is
+ *    singular, so the constructor will never fail. The primary use of the
+ *    LU decomposition is in the solution of square systems of simultaneous
+ *    linear equations. This will fail if isNonsingular() returns false.

+/**
+ * <code>
+ * Header/Footer Formatting Syntax taken from Office Open XML Part 4 - Markup Language Reference, page 1970:.
+ *
+ * There are a number of formatting codes that can be written inline with the actual header / footer text, which
+ * affect the formatting in the header or footer.
+ *
+ * Example: This example shows the text "Center Bold Header" on the first line (center section), and the date on
+ * the second line (center section).
+ *         &CCenter &"-,Bold"Bold&"-,Regular"Header_x000A_&D
+ *
+ * General Rules:
+ * There is no required order in which these codes must appear.
+ *
+ * The first occurrence of the following codes turns the formatting ON, the second occurrence turns it OFF again:
+ * - strikethrough
+ * - superscript
+ * - subscript
+ * Superscript and subscript cannot both be ON at same time. Whichever comes first wins and the other is ignored,
+ * while the first is ON.
+ * &L - code for "left section" (there are three header / footer locations, "left", "center", and "right"). When

+# Changelog
+
+All notable changes to this project will be documented in this file, in reverse chronological order by release.
+
+## 1.0.1 - 2016-08-06
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Updated all `@return self` annotation references in interfaces to use
+  `@return static`, which more closelly follows the semantics of the
+  specification.
+- Updated the `MessageInterface::getHeaders()` return annotation to use the
+  value `string[][]`, indicating the format is a nested array of strings.
+- Updated the `@link` annotation for `RequestInterface::withRequestTarget()`
+  to point to the correct section of RFC 7230.
+- Updated the `ServerRequestInterface::withUploadedFiles()` parameter annotation
+  to add the parameter name (`$uploadedFiles`).
+- Updated a `@throws` annotation for the `UploadedFileInterface::moveTo()`
+  method to correctly reference the method parameter (it was referencing an
+  incorrect parameter name previously).
+
+## 1.0.0 - 2016-05-18
+
+Initial stable release; reflects accepted PSR-7 specification.

+PSR Http Message
+================
+
+This repository holds all interfaces/classes/traits related to
+[PSR-7](http://www.php-fig.org/psr/psr-7/).
+
+Note that this is not a HTTP message implementation of its own. It is merely an
+interface that describes a HTTP message. See the specification for more details.
+
+Usage
+-----
+
+Before reading the usage guide we recommend reading the PSR-7 interfaces method list:

+### PSR-7 Usage
+
+All PSR-7 applications comply with these interfaces 
+They were created to establish a standard between middleware implementations.
+
+> `RequestInterface`, `ServerRequestInterface`, `ResponseInterface` extend `MessageInterface`  because the `Request` and the `Response` are `HTTP Messages`.
+> When using `ServerRequestInterface`, both `RequestInterface` and `Psr\Http\Message\MessageInterface` methods are considered.
+
+
+The following examples will illustrate how basic operations are done in PSR-7.
+
+##### Examples
+
+
+For this examples to work (at least) a PSR-7 implementation package is required. (eg: zendframework/zend-diactoros, guzzlehttp/psr7, slim/slim, etc)
+All PSR-7 implementations should have the same behaviour.
+
+The following will be assumed: 
+`$request` is an object of `Psr\Http\Message\RequestInterface` and
+
+`$response` is an object implementing `Psr\Http\Message\RequestInterface`
+
+
+### Working with HTTP Headers
+
+#### Adding headers to response:
+
+```php
+$response->withHeader('My-Custom-Header', 'My Custom Message');
+```
+
+#### Appending values to headers
+
+```php
+$response->withAddedHeader('My-Custom-Header', 'The second message');
+```
+
+#### Checking if header exists:
+
+```php
+$request->hasHeader('My-Custom-Header'); // will return false
+$response->hasHeader('My-Custom-Header'); // will return true
+```
+
+> Note: My-Custom-Header was only added in the Response
+
+#### Getting comma-separated values from a header (also applies to request)
+
+```php
+// getting value from request headers
+$request->getHeaderLine('Content-Type'); // will return: "text/html; charset=UTF-8"
+// getting value from response headers
+$response->getHeaderLine('My-Custom-Header'); // will return:  "My Custom Message; The second message"
+```
+
+#### Getting array of value from a header (also applies to request)
+```php
+// getting value from request headers
+$request->getHeader('Content-Type'); // will return: ["text/html", "charset=UTF-8"]
+// getting value from response headers
+$response->getHeader('My-Custom-Header'); // will return:  ["My Custom Message",  "The second message"]
+```
+
+#### Removing headers from HTTP Messages
+```php
+// removing a header from Request, removing deprecated "Content-MD5" header
+$request->withoutHeader('Content-MD5'); 
+
+// removing a header from Response
+// effect: the browser won't know the size of the stream
+// the browser will download the stream till it ends
+$response->withoutHeader('Content-Length');
+```
+
+### Working with HTTP Message Body
+
+When working with the PSR-7 there are two methods of implementation:
+#### 1. Getting the body separately
+
+> This method makes the body handling easier to understand and is useful when repeatedly calling body methods. (You only call `getBody()` once). Using this method mistakes like `$response->write()` are also prevented.
+
+```php
+$body = $response->getBody();
+// operations on body, eg. read, write, seek
+// ...
+// replacing the old body
+$response->withBody($body); 
+// this last statement is optional as we working with objects
+// in this case the "new" body is same with the "old" one
+// the $body variable has the same value as the one in $request, only the reference is passed
+```
+
+#### 2. Working directly on response
+
+> This method is useful when only performing few operations as the `$request->getBody()` statement fragment is required
+
+```php
+$response->getBody()->write('hello');
+```
+
+### Getting the body contents
+
+The following snippet gets the contents of a stream contents.
+> Note: Streams must be rewinded, if content was written into streams, it will be ignored when calling `getContents()` because the stream pointer is set to the last character, which is `\0` - meaning end of stream.
+```php 
+$body = $response->getBody();
+$body->rewind(); // or $body->seek(0);
+$bodyText = $body->getContents();
+```
+> Note: If `$body->seek(1)` is called before `$body->getContents()`, the first character will be ommited as the starting pointer is set to `1`, not `0`. This is why using `$body->rewind()` is recommended.
+
+### Append to body
+
+```php
+$response->getBody()->write('Hello'); // writing directly
+$body = $request->getBody(); // which is a `StreamInterface`
+$body->write('xxxxx');
+```
+
+### Prepend to body
+Prepending is different when it comes to streams. The content must be copied before writing the content to be prepended.
+The following example will explain the behaviour of streams.
+
+```php
+// assuming our response is initially empty
+$body = $repsonse->getBody();
+// writing the string "abcd"
+$body->write('abcd');
+
+// seeking to start of stream
+$body->seek(0);
+// writing 'ef'
+$body->write('ef'); // at this point the stream contains "efcd"
+```
+
+#### Prepending by rewriting separately
+
+```php
+// assuming our response body stream only contains: "abcd"
+$body = $response->getBody();
+$body->rewind();
+$contents = $body->getContents(); // abcd
+// seeking the stream to beginning
+$body->rewind();
+$body->write('ef'); // stream contains "efcd"
+$body->write($contents); // stream contains "efabcd"
+```
+
+> Note: `getContents()` seeks the stream while reading it, therefore if the second `rewind()` method call was not present the stream would have resulted in `abcdefabcd` because the `write()` method appends to stream if not preceeded by `rewind()` or `seek(0)`.
+
+#### Prepending by using contents as a string
+```php
+$body = $response->getBody();
+$body->rewind();
+$contents = $body->getContents(); // efabcd
+$contents = 'ef'.$contents;
+$body->rewind();
+$body->write($contents);
+```

+PHP FIG Simple Cache PSR
+========================
+
+This repository holds all interfaces related to PSR-16.
+
+Note that this is not a cache implementation of its own. It is merely an interface that describes a cache implementation. See [the specification](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-16-simple-cache.md) for more details.
+
+You can find implementations of the specification by looking for packages providing the [psr/simple-cache-implementation](https://packagist.org/providers/psr/simple-cache-implementation) virtual package.

+如何贡献我的源代码
+===
+
+此文档介绍了 ThinkPHP 团队的组成以及运转机制，您提交的代码将给 ThinkPHP 项目带来什么好处，以及如何才能加入我们的行列。
+
+## 通过 Github 贡献代码
+
+ThinkPHP 目前使用 Git 来控制程序版本，如果你想为 ThinkPHP 贡献源代码，请先大致了解 Git 的使用方法。我们目前把项目托管在 GitHub 上，任何 GitHub 用户都可以向我们贡献代码。
+
+参与的方式很简单，`fork`一份 ThinkPHP 的代码到你的仓库中，修改后提交，并向我们发起`pull request`申请，我们会及时对代码进行审查并处理你的申请。审查通过后，你的代码将被`merge`进我们的仓库中，这样你就会自动出现在贡献者名单里了，非常方便。
+
+我们希望你贡献的代码符合：
+
+* ThinkPHP 的编码规范
+* 适当的注释，能让其他人读懂
+* 遵循 Apache2 开源协议
+
+**如果想要了解更多细节或有任何疑问，请继续阅读下面的内容**
+
+### 注意事项
+
+* 本项目代码格式化标准选用 [**PSR-2**](http://www.kancloud.cn/thinkphp/php-fig-psr/3141)；
+* 类名和类文件名遵循 [**PSR-4**](http://www.kancloud.cn/thinkphp/php-fig-psr/3144)；
+* 对于 Issues 的处理，请使用诸如 `fix #xxx(Issue ID)` 的 commit title 直接关闭 issue。
+* 系统会自动在 PHP 5.4 5.5 5.6 7.0 和 HHVM 上测试修改，其中 HHVM 下的测试容许报错，请确保你的修改符合 PHP 5.4 ~ 5.6 和 PHP 7.0 的语法规范；
+* 管理员不会合并造成 CI faild 的修改，若出现 CI faild 请检查自己的源代码或修改相应的[单元测试文件](tests)；
+
+## GitHub Issue
+
+GitHub 提供了 Issue 功能，该功能可以用于：
+
+* 提出 bug
+* 提出功能改进
+* 反馈使用体验
+
+该功能不应该用于：
+
+ * 提出修改意见（涉及代码署名和修订追溯问题）
+ * 不友善的言论
+
+## 快速修改
+
+**GitHub 提供了快速编辑文件的功能**
+
+1. 登录 GitHub 帐号；
+2. 浏览项目文件，找到要进行修改的文件；
+3. 点击右上角铅笔图标进行修改；
+4. 填写 `Commit changes` 相关内容（Title 必填）；
+5. 提交修改，等待 CI 验证和管理员合并。
+
+**若您需要一次提交大量修改，请继续阅读下面的内容**
+
+## 完整流程
+
+1. `fork`本项目；
+2. 克隆(`clone`)你 `fork` 的项目到本地；
+3. 新建分支(`branch`)并检出(`checkout`)新分支；
+4. 添加本项目到你的本地 git 仓库作为上游(`upstream`)；
+5. 进行修改，若你的修改包含方法或函数的增减，请记得修改[单元测试文件](tests)；
+6. 变基（衍合 `rebase`）你的分支到上游 master 分支；
+7. `push` 你的本地仓库到 GitHub；
+8. 提交 `pull request`；
+9. 等待 CI 验证（若不通过则重复 5~7，不需要重新提交 `pull request`，GitHub 会自动更新你的 `pull request`）；
+10. 等待管理员处理，并及时 `rebase` 你的分支到上游 master 分支（若上游 master 分支有修改）。
+
+*若有必要，可以 `git push -f` 强行推送 rebase 后的分支到自己的 `fork`*
+
+*绝对不可以使用 `git push -f` 强行推送修改到上游*
+
+### 注意事项
+
+* 若对上述流程有任何不清楚的地方，请查阅 GIT 教程，如 [这个](http://backlogtool.com/git-guide/cn/)；
+* 对于代码**不同方面**的修改，请在自己 `fork` 的项目中**创建不同的分支**（原因参见`完整流程`第9条备注部分）；
+* 变基及交互式变基操作参见 [Git 交互式变基](http://pakchoi.me/2015/03/17/git-interactive-rebase/)
+
+## 推荐资源
+
+### 开发环境
+
+* XAMPP for Windows 5.5.x
+* WampServer (for Windows)
+* upupw Apache PHP5.4 ( for Windows)
+

+## 测试目录结构
+
+测试文件主要在 tests 文件下面，主要有以下几个文件夹
+
+- conf 测试环境配置文件。
+- script 测试环境配置脚本。
+- thinkphp 测试用例和相关文件，与项目文件夹结构一致。
+- mock.php 测试入口文件。
+
+## 主要测试流程
+
+thinkphp5 的测试的主要流程是跟 thinkphp 的系统流程是相似的，大体的流程为：
+
+1. 引用 mock.php 文件加载框架
+
+2. 根据文件目录，添加测试文件
+
+3. 执行单元测试，输出结果
+
+## 测试举例
+
+例如测试 thinkphp 里的 apc 缓存，将分为以下几个过程：
+
+1. 创建 apcTest.php 文件
+
+该文件应与 apc.php 目录路径 `thinkphp/library/think/cache/driver` 一致，命名空间与目录所在一致，并引用 `PHPUnit_Framework_TestCase`。
+
+  ```php
+  <?php
+
+  namespace tests\thinkphp\library\think\cache\driver;
+
+  class apcTest extends \PHPUnit_Framework_TestCase
+  {
+      //设定基境
+      public function setUp()
+      {
+      }
+  }
+  ```
+
+2. 编写测试文件
+
+  - 引用 app、config 和 cache
+
+  ```php
+  use think\app;
+  use think\cache;
+  use think\config;
+  ```
+  - 在 setUp 函数中设定 require 条件
+
+  ```php
+  if(!extension_loaded('apc')){
+      $this->markTestSkipped('apc扩展不可用！');
+  };
+  ```
+
+  - 编写测试用例
+
+  *具体写法参照 [PHPUnit 官方文档](https://phpunit.de/manual/4.8/zh_cn/index.html)*
+
+  ```php
+  public function testGet()
+  {
+      App::run();
+      $this->assertInstanceOf(
+          '\think\cache\driver\Apc',
+          Cache::connect(['type' => 'apc', 'expire' => 1])
+      );
+      $this->assertTrue(Cache::set('key', 'value'));
+      $this->assertEquals('value', Cache::get('key'));
+      $this->assertTrue(Cache::rm('key'));
+      $this->assertFalse(Cache::get('key'));
+      $this->assertTrue(Cache::clear('key'));
+      Config::reset();
+  }
+  ```
+
+3. 执行单元测试命令
+
+  在项目根目录执行
+
+  ```bash
+  $ phpunit
+  ```
+
+  若想看到所有结果，请添加-v参数
+
+  ```bash
+  $ phpunit -v
+  ```
+
+4. 输出结果
+
+## 相关文档
+
+[各个部分单元测试说明](http://www.kancloud.cn/brother_simon/tp5_test/96971 "各部分单元测试说明")
+
+## 大家一起来
+
+单元测试的内容会跟框架同步，测试内容方方面面，是一个相对复杂的模块，同时也是一个值得重视的部分。希望大家能够多多提出意见，多多参与。如果你有任何问题或想法，可以随时提 issue，我们期待着收到听大家的质疑和讨论。
+
+## 任务进度
+
+单元测试任务进度，请大家认领模块
