What is Composer in PHP

Composer is a dependency manager for PHP, enabling developers to manage libraries and packages efficiently. It allows you to declare the libraries your project depends on and handles the installation and autoloading of those libraries.

By using Composer, developers can ensure that their PHP applications have the right dependencies in the correct versions, simplifying project management and maintenance.


        {
            "require": {
                "monolog/monolog": "^2.0"
            }
        }

In the above example, we define a JSON file called composer.json where we specify the dependencies required for our PHP project, in this case, the Monolog library for logging.
