What is Composer?

Editorial review

Composer manages dependencies for PHP projects. Define what packages you need, and Composer resolves versions, downloads code, and generates autoload files-the package manager that modernized PHP development. The ecosystem on Packagist covers most needs. Version constraints ensure compatibility. The autoloader eliminates manual includes. PHP developers don't debate whether to use Composer-it's how modern PHP projects manage dependencies, period.
