How To Create MVC For PHP &PHP 7 Using ( Router Technique ) - Udemy

In the context of a server-side web application, a routing system is the part of the web application that maps an HTTP request to a request handler (function/method). An HTTP request consists of a header and optionally a body. The header contains information about the request for example the method, path and host. Some methods like GET, HEAD, and OPTIONS do not make use of the request body while others like POST, PUT, and PATCH use it to pass data from a client to a server.

Using a routing system allows us to structure our application in a better way instead of designating each request to a file.

A routing system works by mapping an HTTP request to a request handler based on the request method and path specified in the URL of the request. This is exactly what we are going to build in this tutorial.
