PHP Composer is a dependency management tool for PHP, widely used in modern PHP development. It allows developers to manage the libraries their project depends on in an efficient manner. Composer automates the process of installing, updating, and managing libraries and their dependencies. It works by declaring the libraries in a file called composer.json, then Composer handles downloading and installing these libraries into your project. This tool streamlines the development process, ensuring that all necessary components are present and up-to-date for PHP applications.
