The Slim Micro Framework for PHP 5 is a micro framework that enables developers to quickly write RESTful web applications and APIs. Emphasize is placed on micro because Slim is just that â€” a lightweight and nimble PHP framework used to build smaller web applications and APIs. Unlike the larger frameworks CodeIgniter and Symfony, Slim forgoes controllers and abstract components for simplicity and ease-of-use.
A Slim Framework web application can be built with only a single file. Over time, however, projects grow in scope and size; better organization becomes necessary. Slim does not use controllers to organize application methods or routes; controllers are beyond Slimâ€™s concern.
