The composer.json file declares your project dependencies and autoload rules.
Run composer install to download and set up dependencies.
Autoloading follows PSR-4 standards, letting you load classes without manual requires.
Use composer update to update packages.
Composer handles version constraints, so your dependencies stay stable.

💡 Tip: Always commit your composer.json and composer.lock files to version control, but ignore the vendor/ folder.
