Composer

Composer is a dependency management tool for PHP that allows developers to declare, install, and update the libraries and packages their projects depend on. It uses a composer.json file to specify project dependencies and configuration, automating the process of managing external code and ensuring consistent environments across development and production.

Also known as: Composer.json, PHP Composer, Composer Dependency Manager, Composer PHP, composer

Why learn Composer?

Developers should use Composer when building PHP applications that rely on external libraries or frameworks, such as Laravel, Symfony, or WordPress plugins, to streamline dependency handling and avoid manual installation. It is essential for modern PHP development to ensure version compatibility, facilitate team collaboration, and integrate with continuous deployment pipelines.
