What’s the Composer purpose

Composer is an application-level package manager for PHP that provides a standard format for managing dependencies of PHP software and required libraries. Composer is strongly inspired by Node.js package manager npm, and the Ruby one called bundler.

You can run Composer from the command line and installs dependencies. It also allows users to install PHP applications that are available on Packagist, using the main repository containing available packages.
