Composer

Composer is a tool for managing PHP software libraries and dependencies. It helps developers specify the packages their project needs, and then automatically downloads and maintains those packages, ensuring compatibility. Think of it as a digital organizer that keeps all the external code your project relies on in sync and up-to-date, simplifying the process of working with multiple libraries. Composer also manages version control, so you can specify exact versions of packages, avoiding conflicts. Overall, it streamlines the development process, saving time and reducing errors by handling complex dependency management efficiently.
