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). [](https://travis-ci.com/php/php-src) [](https://ci.appveyor.com/project/php/php-src) [](https://dev.azure.com/phpazuredevops/php/_build/latest?definitionId=1&branchName=master) [](https://bugs.chromium.org/p/oss-fuzz/issues/list?sort=-opened&can=1&q=proj:php) ## Documentation The PHP manual is available at [php.net/docs](https://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://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 Contributions are most welcome by forking the [GitHub repository](https://github.com/php/php-src) 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 **do not** require an RFC but require a bug tracker ticket. Open a ticket at [bugs.php.net](https://bugs.php.net) and reference the bug id using `#NNNNNN`. Fix #55371: get_magic_quotes_gpc() throws deprecation warning After removing magic quotes, the get_magic_quotes_gpc function caused a deprecated warning. get_magic_quotes_gpc can be used to detect the magic_quotes behavior and therefore should not raise a warning at any time. The patch removes this warning. See [Git workflow](https://wiki.php.net/vcs/gitworkflow) for more details on the pull request workflow. ### Guidelines for contributors See further documents in the repository for more information on how to contribute: - [Contributing to PHP](/CONTRIBUTING.md) - [PHP coding standards](/CODING_STANDARDS.md) - [Mailinglist rules](/docs/mailinglist-rules.md) - [PHP release process](/docs/release-process.md) ## Credits For the list of people who've put work into PHP, please see the [PHP credits page](https://php.net/credits.php).
