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.
