25PCRE2 LICENCE
26-------------
27
28PCRE2 is a library of functions to support regular expressions whose syntax
29and semantics are as close as possible to those of the Perl 5 language.
30
31Releases 10.00 and above of PCRE2 are distributed under the terms of the "BSD"
32licence, as specified below, with one exemption for certain binary
33redistributions. The documentation for PCRE2, supplied in the "doc" directory,
34is distributed under the same terms as the software itself. The data in the
35testdata directory is not copyrighted and is in the public domain.
36
37The basic library functions are written in C and are freestanding. Also
38included in the distribution is a just-in-time compiler that can be used to
39optimize pattern matching. This is an optional feature that can be omitted when
40the library is built.

112The second condition in the BSD licence (covering binary redistributions) does
113not apply all the way down a chain of software. If binary package A includes
114PCRE2, it must respect the condition, but if package B is software that
115includes package A, the condition is not imposed on package B unless it uses
116PCRE2 independently.

154
155The crypt_blowfish homepage is:

157http://www.openwall.com/crypt/
158
159This code comes from John the Ripper password cracker, with reentrant
160and crypt(3) interfaces added, but optimizations specific to password
161cracking removed.
162
163Written by Solar Designer <solar at openwall.com> in 1998-2011.
164No copyright is claimed, and the software is hereby placed in the public
165domain. In case this attempt to disclaim copyright and place the software
166in the public domain is deemed null and void, then the software is
167Copyright (c) 1998-2011 Solar Designer and it is hereby released to the
168general public under the following terms:
169
170Redistribution and use in source and binary forms, with or without
171modification, are permitted.

173There's ABSOLUTELY NO WARRANTY, express or implied.
174
175It is my intent that you should be able to use this on your system,
176as part of a software package, or anywhere else to improve security,
177ensure compatibility, or for any other purpose. I would appreciate
178it if you give credit where it is due and keep your modifications in
179the public domain as well, but I don't require that in order to let
180you place this code and any modifications you make under a license
181of your choice.
182
183This implementation is mostly compatible with OpenBSD's bcrypt.c (prefix
184"$2a$") by Niels Provos <provos at citi.umich.edu>, and uses some of his
185ideas. The password hashing algorithm was designed by David Mazieres
186<dm at lcs.mit.edu>. For more information on the level of compatibility,
187please refer to the comments in BF_set_key() and to the crypt(3) man page
188included in the crypt_blowfish tarball.
189
190There's a paper on the algorithm that explains its design decisions:
191
192http://www.usenix.org/events/usenix99/provos.html
193
194Some of the tricks in BF_ROUND might be inspired by Eric Young's
195Blowfish library (I can't be sure if I would think of something if I
196hadn't seen his code).

205Mersenne Twister random number generator -- a C++ class MTRand
206Based on code by Makoto Matsumoto, Takuji Nishimura, and Shawn Cokus
207Richard J. Wagner  v1.0  15 May 2003  rjwagner@writeme.com
208
209The Mersenne Twister is an algorithm for generating random numbers.  It
210was designed with consideration of the flaws in various other generators.
211The period, 2^19937-1, and the order of equidistribution, 623 dimensions,
212are far greater.  The generator is also fast; it avoids multiplication and
213division, and it benefits from caches and pipelines.  For more information
214see the inventors' web page at http://www.math.keio.ac.jp/~matumoto/emt.html

10# The PHP Interpreter
11
12PHP is a popular general-purpose scripting language that is especially suited to
13web development. Fast, flexible and pragmatic, PHP powers everything from your
14blog to the most popular websites in the world. PHP is distributed under the
15[PHP License v3.01](LICENSE).

20
21## Documentation
22
23The PHP manual is available at [php.net/docs](https://php.net/docs).
24
25## Installation
26
27### Prebuilt packages and binaries
28
29Prebuilt packages and binaries can be used to get up and running fast with PHP.
30
31For Windows, the PHP binaries can be obtained from
32[windows.php.net](https://windows.php.net). After extracting the archive the
33`*.exe` files are ready to use.
34
35For other systems, see the [installation chapter](https://php.net/install).
36
37### Building PHP source code
38
39*For Windows, see [Build your own PHP on Windows](https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2).*
40
41For a minimal PHP build from Git, you will need autoconf, bison, and re2c. For
42a default build, you will additionally need libxml2 and libsqlite3.
43
44On Ubuntu, you can install these using:
45
46    sudo apt install -y pkg-config build-essential autoconf bison re2c \
47                        libxml2-dev libsqlite3-dev
48
49On Fedora, you can install these using:
50
51    sudo dnf install re2c bison autoconf make libtool ccache libxml2-devel sqlite-devel
52
53Generate configure:
54
55    ./buildconf
56
57Configure your build. `--enable-debug` is recommended for development, see
58`./configure --help` for a full list of options.
59
60    # For development
61    ./configure --enable-debug
62    # For production
63    ./configure
64
65Build PHP. To speed up the build, specify the maximum number of jobs using `-j`:
66
67    make -j4
68
69The number of jobs should usually match the number of available cores, which
70can be determined using `nproc`.
71
72## Testing PHP source code
73
74PHP ships with an extensive test suite, the command `make test` is used after
75successful compilation of the sources to run this test suite.
76
77It is possible to run tests using multiple cores by setting `-jN` in
78`TEST_PHP_ARGS`:
79
80    make TEST_PHP_ARGS=-j4 test
81
82Shall run `make test` with a maximum of 4 concurrent jobs: Generally the maximum
83number of jobs should not exceed the number of cores available.
84
85The [qa.php.net](https://qa.php.net) site provides more detailed info about
86testing and quality assurance.
87
88## Installing PHP built from source
89
90After a successful build (and test), PHP may be installed with:
91
92    make install
93
94Depending on your permissions and prefix, `make install` may need super user
95permissions.
96
97## PHP extensions
98
99Extensions provide additional functionality on top of PHP. PHP consists of many
100essential bundled extensions. Additional extensions can be found in the PHP
101Extension Community Library - [PECL](https://pecl.php.net).
102
103## Contributing
104
105The PHP source code is located in the Git repository at
106[github.com/php/php-src](https://github.com/php/php-src). Contributions are most
107welcome by forking the repository and sending a pull request.
108
109Discussions are done on GitHub, but depending on the topic can also be relayed
110to the official PHP developer mailing list internals@lists.php.net.
111
112New features require an RFC and must be accepted by the developers. See
113[Request for comments - RFC](https://wiki.php.net/rfc) and
114[Voting on PHP features](https://wiki.php.net/rfc/voting) for more information
115on the process.
116
117Bug fixes don't require an RFC. If the bug has a GitHub issue, reference it in
118the commit message using `GH-NNNNNN`. Use `#NNNNNN` for tickets in the old
119[bugs.php.net](https://bugs.php.net) bug tracker.
120
121    Fix GH-7815: php_uname doesn't recognise latest Windows versions
122    Fix #55371: get_magic_quotes_gpc() throws deprecation warning
123
124See [Git workflow](https://wiki.php.net/vcs/gitworkflow) for details on how pull
125requests are merged.
