Dependency Management for PHP

Composer helps you declare, manage, and install dependencies of PHP projects. See [https://getcomposer.org/](https://getcomposer.org/) for more information and documentation. Installation / Usage -------------------- Download and install Composer by following the [official instructions](https://getcomposer.org/download/). For usage, see [the documentation](https://getcomposer.org/doc/). Packages -------- Find public packages on [Packagist.org](https://packagist.org). For private package hosting take a look at [Private Packagist](https://packagist.com). Community --------- Follow [@packagist](https://X.com/packagist) or [@seldaek](https://X.com/seldaek) on X for announcements, or check the [#composerphp](https://X.com/search?q=%23composerphp&src=typed_query&f=live) hashtag. For support, Stack Overflow offers a good collection of [Composer related questions](https://stackoverflow.com/questions/tagged/composer-php), or you can use the [GitHub discussions](https://github.com/composer/composer/discussions). Please note that this project is released with a [Contributor Code of Conduct](https://www.contributor-covenant.org/version/1/4/code-of-conduct/). By participating in this project and its community you agree to abide by those terms. Requirements ------------ #### Latest Composer PHP 7.2.5 or above for the latest version. #### Composer 2.2 LTS (Long Term Support) PHP versions 5.3.2 - 8.1 are still supported via the LTS releases of Composer (2.2.x). If you run the installer or the `self-update` command the appropriate Composer version for your PHP should be automatically selected. #### Binary dependencies - `unzip` (or `7z`/`7zz`) - `gzip` - `tar` - `unrar` - `xz` - Git (`git`) - Mercurial (`hg`) - Fossil (`fossil`) - Perforce (`p4`) - Subversion (`svn`) The need for these binary dependencies may vary depending on individual use cases. For most users, only 2 dependencies are essential for Composer: `unzip` (or `7z`/`7zz`), and `git`. If the [`ext-zip`](https://www.php.net/manual/en/zip.installation.php) extension is available, only `git` is needed, but this is not recommended.
