Composer is a widely-used, open-source dependency manager for PHP that helps developers manage libraries and packages efficiently. It simplifies the process of handling dependencies, ensuring consistency across development, testing, and production environments.

Features of Composer:

• Manages PHP project dependencies automatically, reducing manual overhead.
• Provides a centralized repository, Packagist, to easily discover and integrate libraries.
• Supports semantic versioning to ensure compatibility between dependencies.
• Allows autoloading of classes, streamlining development workflows.
• Facilitates custom scripts for automating project-specific tasks.
