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://travis-ci.com/php/php-src) 18[](https://dev.azure.com/phpazuredevops/php/_build/latest?definitionId=1&branchName=master) 19[](https://bugs.chromium.org/p/oss-fuzz/issues/list?sort=-opened&can=1&q=proj:php) 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. 126 127### Guidelines for contributors 128 129See further documents in the repository for more information on how to 130contribute: 131 132- [Contributing to PHP](/CONTRIBUTING.md) 133- [PHP coding standards](/CODING_STANDARDS.md) 134- [Mailinglist 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://php.net/credits.php). 141
