Composer is a powerful dependency manager for PHP, widely used to streamline project dependencies and package management. Developed by Nils Adermann and Jordi Boggiano, Composer enables developers to efficiently manage PHP libraries, ensuring seamless integration and version control in their projects.

Features of Composer:

• Composer allows for automatic dependency resolution, ensuring that projects use compatible versions of libraries and frameworks.
• With a centralized package repository (Packagist), Composer provides easy access to thousands of PHP packages, simplifying software development.
• Composer supports autoloading, reducing the need for manual `require` or `include` statements, leading to cleaner and more maintainable code.
• It facilitates project isolation by enabling the installation of dependencies in a per-project `vendor` directory, preventing conflicts between different applications.

To check Composer version, run the following commands on your VM:

$ cd /opt

$ sudo ln -s /opt/composer /usr/local/bin/composer

$ composer -V
