Composer

Composer is a tool for PHP dependencies management. It allows you to declare the dependent libraries your project needs and it will install them in your project for you. Composer is not a package manager. Though dealing with "packages" or libraries, it manages them on a per-project basis, installing them in a directory inside your project.

The Composer helps in the following scenarios:

A project depending on a number of libraries.
Some of those libraries depend on other libraries.
You declare the things you depend on.
Composer finds out which versions of which packages need to be installed, and installs them (meaning it downloads them into your project).
