Manage dependencies for PHP projects with Composer, which lets developers declare, install, and update packages.
About Composer
Composer is a dependency manager for PHP projects. It lets developers declare the packages a project depends on, then install and manage them. Public packages are found on Packagist.org. The source is open source under the MIT License.
The latest Composer requires PHP 7.2.5 or above. PHP versions 5.3.2 to 8.1 are supported through the Composer 2.2 LTS release line. The installer and self-update command should select the appropriate version for the PHP installed. For most users, unzip (or 7z/7zz) and git are essential. Other binary tools, such as tar, gzip, Mercurial, or Subversion, may be needed depending on the use case. Private package hosting is not part of Composer itself; the source points to Private Packagist for that.
