Composer - an excellent package manager

Primary source - Getcomposer 

Template - No 

Download link - Download Composer

Composer is an application-level package manager for the PHP programming language that provides a standard format for managing dependencies of PHP software and required libraries. It was developed by Nils Adermann andJordi Boggiano, who continue to manage the project.

Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

In my opinion composer is best package manager and very secure and manages all it task efficiently but one thing I not found in compose is that It has only command line interface and no GUI Interface.
