PCRE2 LICENCE
-------------

PCRE2 is a library of functions to support regular expressions whose syntax
and semantics are as close as possible to those of the Perl 5 language.

Releases 10.00 and above of PCRE2 are distributed under the terms of the "BSD"
licence, as specified below, with one exemption for certain binary
redistributions. The documentation for PCRE2, supplied in the "doc" directory,
is distributed under the same terms as the software itself. The data in the
testdata directory is not copyrighted and is in the public domain.

The basic library functions are written in C and are freestanding. Also
included in the distribution is a just-in-time compiler that can be used to
optimize pattern matching. This is an optional feature that can be omitted when
the library is built.

EXEMPTION FOR BINARY LIBRARY-LIKE PACKAGES
------------------------------------------

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

5. ext/standard crypt's blowfish implementation

The crypt_blowfish homepage is:

http://www.openwall.com/crypt/

This code comes from John the Ripper password cracker, with reentrant
and crypt(3) interfaces added, but optimizations specific to password
cracking removed.

Written by Solar Designer <solar at openwall.com> in 1998-2011.
No copyright is claimed, and the software is hereby placed in the public
domain. In case this attempt to disclaim copyright and place the software
in the public domain is deemed null and void, then the software is
Copyright (c) 1998-2011 Solar Designer and it is hereby released to the
general public under the following terms:

Redistribution and use in source and binary forms, with or without
modification, are permitted.

There's ABSOLUTELY NO WARRANTY, express or implied.

It is my intent that you should be able to use this on your system,
as part of a software package, or anywhere else to improve security,
ensure compatibility, or for any other purpose. I would appreciate
it if you give credit where it is due and keep your modifications in
the public domain as well, but I don't require that in order to let
you place this code and any modifications you make under a license
of your choice.

This implementation is mostly compatible with OpenBSD's bcrypt.c (prefix
"$2a$") by Niels Provos <provos at citi.umich.edu>, and uses some of his
ideas. The password hashing algorithm was designed by David Mazieres
<dm at lcs.mit.edu>. For more information on the level of compatibility,
please refer to the comments in BF_set_key() and to the crypt(3) man page
included in the crypt_blowfish tarball.

There's a paper on the algorithm that explains its design decisions:

http://www.usenix.org/events/usenix99/provos.html

Some of the tricks in BF_ROUND might be inspired by Eric Young's
Blowfish library (I can't be sure if I would think of something if I
hadn't seen his code).


6. ext/standard/rand

The following php_mt_...() functions are based on a C++ class MTRand by
Richard J. Wagner. For more information see the web page at
http://www-personal.engin.umich.edu/~wagnerr/MersenneTwister.html

Mersenne Twister random number generator -- a C++ class MTRand
Based on code by Makoto Matsumoto, Takuji Nishimura, and Shawn Cokus
Richard J. Wagner  v1.0  15 May 2003  rjwagner@writeme.com

The Mersenne Twister is an algorithm for generating random numbers.  It
was designed with consideration of the flaws in various other generators.
The period, 2^19937-1, and the order of equidistribution, 623 dimensions,
are far greater.  The generator is also fast; it avoids multiplication and
division, and it benefits from caches and pipelines.  For more information
see the inventors' web page at http://www.math.keio.ac.jp/~matumoto/emt.html

# The PHP Interpreter

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

## Documentation

The PHP manual is available at [php.net/docs](https://www.php.net/docs).

## Installation

### Prebuilt packages and binaries

Prebuilt packages and binaries can be used to get up and running fast with PHP.

For Windows, the PHP binaries can be obtained from
[windows.php.net](https://windows.php.net). After extracting the archive the
`*.exe` files are ready to use.

For other systems, see the [installation chapter](https://www.php.net/install).

### Building PHP source code

*For Windows, see [Build your own PHP on Windows](https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2).*

For a minimal PHP build from Git, you will need autoconf, bison, and re2c. For
a default build, you will additionally need libxml2 and libsqlite3.

On Ubuntu, you can install these using:

    sudo apt install -y pkg-config build-essential autoconf bison re2c \
                        libxml2-dev libsqlite3-dev

On Fedora, you can install these using:

    sudo dnf install re2c bison autoconf make libtool ccache libxml2-devel sqlite-devel

Generate configure:

    ./buildconf

Configure your build. `--enable-debug` is recommended for development, see
`./configure --help` for a full list of options.

    # For development
    ./configure --enable-debug
    # For production
    ./configure

Build PHP. To speed up the build, specify the maximum number of jobs using `-j`:

    make -j4

The number of jobs should usually match the number of available cores, which
can be determined using `nproc`.

## Testing PHP source code

PHP ships with an extensive test suite, the command `make test` is used after
successful compilation of the sources to run this test suite.

It is possible to run tests using multiple cores by setting `-jN` in
`TEST_PHP_ARGS`:

    make TEST_PHP_ARGS=-j4 test

Shall run `make test` with a maximum of 4 concurrent jobs: Generally the maximum
number of jobs should not exceed the number of cores available.

The [qa.php.net](https://qa.php.net) site provides more detailed info about
testing and quality assurance.

## Installing PHP built from source

After a successful build (and test), PHP may be installed with:

    make install

Depending on your permissions and prefix, `make install` may need super user
permissions.

## PHP extensions

Extensions provide additional functionality on top of PHP. PHP consists of many
essential bundled extensions. Additional extensions can be found in the PHP
Extension Community Library - [PECL](https://pecl.php.net).

## Contributing

The PHP source code is located in the Git repository at
[github.com/php/php-src](https://github.com/php/php-src). Contributions are most
welcome by forking the repository and sending a pull request.

Discussions are done on GitHub, but depending on the topic can also be relayed
to the official PHP developer mailing list internals@lists.php.net.

New features require an RFC and must be accepted by the developers. See
[Request for comments - RFC](https://wiki.php.net/rfc) and
[Voting on PHP features](https://wiki.php.net/rfc/voting) for more information
on the process.

Bug fixes don't require an RFC. If the bug has a GitHub issue, reference it in
the commit message using `GH-NNNNNN`. Use `#NNNNNN` for tickets in the old
[bugs.php.net](https://bugs.php.net) bug tracker.

    Fix GH-7815: php_uname doesn't recognise latest Windows versions
    Fix #55371: get_magic_quotes_gpc() throws deprecation warning

See [Git workflow](https://wiki.php.net/vcs/gitworkflow) for details on how pull
requests are merged.
