What is the purpose of Composer in PHP?

Composer is a dependency management tool for PHP, used to manage third-party libraries and dependencies in a project. It automatically resolves the project’s dependencies and downloads the required packages from an official package repository (Packagist). Composer also handles autoloading, making it easier and more efficient to include third-party libraries and classes. With Composer, developers can easily manage dependencies in their projects, ensuring consistency in the versions of third-party libraries used, and improving the maintainability and reliability of the project.
