Slim

PHP micro framework for web applications and APIs built around a router, middleware and PSR-7 HTTP messages.

Slim is a PHP micro framework for web applications and APIs, built around a router, middleware and PSR-7 HTTP messages. It has no view layer of its own. Templates come from Twig-View or the PHP-View package, and any PSR-7 implementation can supply the message objects. Slim ships no database layer; the docs carry a Doctrine cookbook entry.

Applications run behind a web server with URL rewriting. A new project starts from the skeleton package. The documentation covers a dedicated server and shared hosting with Apache.
