What is Composer?
Composer is an open-source dependency manager specifically designed for PHP projects. It helps developers manage the external libraries and packages their applications rely on. This tool simplifies the process of integrating and maintaining third-party code within their development environment. Developers use Composer to declare the specific libraries their project requires, and it then automatically finds, downloads, and installs them. It also assists in updating these libraries to their latest compatible versions, ensuring that all project dependencies remain current and function correctly.
