Slim is a PHP micro framework that helps you quickly write simple yet powerful web applications and APIs.
Slim provides a fast and powerful router that maps route callbacks to specific HTTP request methods and URIs. It supports parameters and pattern matching.
Build your application with concentric middleware to tweak the HTTP request and response objects around your Slim app.
Slim supports any PSR-7 HTTP message implementation so you may inspect and manipulate HTTP message method, status, URI, headers, cookies, and body.
Slim supports dependency injection so you have complete control of your external tools. Use any Container-Interop container.
