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). 16 17[](https://github.com/php/php-src/actions/workflows/push.yml) 18[](https://bugs.chromium.org/p/oss-fuzz/issues/list?sort=-opened&can=1&q=proj:php) 19 20## Documentation 21 22The PHP manual is available at [php.net/docs](https://www.php.net/docs). 23 24## Installation 25 26### Prebuilt packages and binaries 27 28Prebuilt packages and binaries can be used to get up and running fast with PHP. 29 30For Windows, the PHP binaries can be obtained from 31[windows.php.net](https://windows.php.net). After extracting the archive the 32`*.exe` files are ready to use. 33 34For other systems, see the [installation chapter](https://www.php.net/install). 35 36### Building PHP source code 37 38*For Windows, see [Build your own PHP on Windows](https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2).* 39 40For a minimal PHP build from Git, you will need autoconf, bison, and re2c. For 41a default build, you will additionally need libxml2 and libsqlite3. 42 43On Ubuntu, you can install these using: 44 45 sudo apt install -y pkg-config build-essential autoconf bison re2c \ 46 libxml2-dev libsqlite3-dev 47 48On Fedora, you can install these using: 49 50 sudo dnf install re2c bison autoconf make libtool ccache libxml2-devel sqlite-devel 51 52Generate configure: 53 54 ./buildconf 55 56Configure your build. `--enable-debug` is recommended for development, see 57`./configure --help` for a full list of options. 58 59 # For development 60 ./configure --enable-debug 61 # For production 62 ./configure 63 64Build PHP. To speed up the build, specify the maximum number of jobs using `-j`: 65 66 make -j4 67 68The number of jobs should usually match the number of available cores, which 69can be determined using `nproc`. 70 71## Testing PHP source code 72 73PHP ships with an extensive test suite, the command `make test` is used after 74successful compilation of the sources to run this test suite. 75 76It is possible to run tests using multiple cores by setting `-jN` in 77`TEST_PHP_ARGS`: 78 79 make TEST_PHP_ARGS=-j4 test 80 81Shall run `make test` with a maximum of 4 concurrent jobs: Generally the maximum 82number of jobs should not exceed the number of cores available. 83 84The [qa.php.net](https://qa.php.net) site provides more detailed info about 85testing and quality assurance. 86 87## Installing PHP built from source 88 89After a successful build (and test), PHP may be installed with: 90 91 make install 92 93Depending on your permissions and prefix, `make install` may need super user 94permissions. 95 96## PHP extensions 97 98Extensions provide additional functionality on top of PHP. PHP consists of many 99essential bundled extensions. Additional extensions can be found in the PHP 100Extension Community Library - [PECL](https://pecl.php.net). 101 102## Contributing 103 104The PHP source code is located in the Git repository at 105[github.com/php/php-src](https://github.com/php/php-src). Contributions are most 106welcome by forking the repository and sending a pull request. 107 108Discussions are done on GitHub, but depending on the topic can also be relayed 109to the official PHP developer mailing list internals@lists.php.net. 110 111New features require an RFC and must be accepted by the developers. See 112[Request for comments - RFC](https://wiki.php.net/rfc) and 113[Voting on PHP features](https://wiki.php.net/rfc/voting) for more information 114on the process. 115 116Bug fixes don't require an RFC. If the bug has a GitHub issue, reference it in 117the commit message using `GH-NNNNNN`. Use `#NNNNNN` for tickets in the old 118[bugs.php.net](https://bugs.php.net) bug tracker. 119 120 Fix GH-7815: php_uname doesn't recognise latest Windows versions 121 Fix #55371: get_magic_quotes_gpc() throws deprecation warning 122 123See [Git workflow](https://wiki.php.net/vcs/gitworkflow) for details on how pull 124requests are merged. 125 126### Guidelines for contributors 127 128See further documents in the repository for more information on how to 129contribute: 130 131- [Contributing to PHP](/CONTRIBUTING.md) 132- [PHP coding standards](/CODING_STANDARDS.md) 133- [Internal documentation](https://php.github.io/php-src/) 134- [Mailing list rules](/docs/mailinglist-rules.md) 135- [PHP release process](/docs/release-process.md) 136 137## Credits 138 139For the list of people who've put work into PHP, please see the 140[PHP credits page](https://www.php.net/credits.php). 141
