Developing a Router in Your Own MVC Framework

Now you need to develop a router. It is a class that will take an array of routes, take the requested URL, and determine which route corresponds to the given URL. After finding the matching route, our class should get the URL parts that correspond to the route parameters.

Let our router return as its result an object of the Track class, containing the name of the controller that should be called for this request, the name of the action, and the parameters from the URL.

Let our Track class have properties controller, action and params, which are read-only:

<?php
	namespace Core;
	
	class Track
	{
		private $controller;
		private $action;
		private $params;
		
		public function __construct($controller, $action, $params)
		{
			$this->controller = $controller;
			$this->action = $action;
			$this->params = $params;
		}
		
		public function __get($property)
		{
			return $this->$property;
		}
	}
?>

Example

For example, let's say the address bar contains /test/1/2/. Let's say we have a route that matches this address:

<?php
	new Route('/test/:var1/:var2/', 'test', 'index');
?>

This means that the controller name will be test, the action name - index, and the parameter array will be the following:

<?php
	['var1' => 1, 'var2' => 2]
?>

The goal of this lesson is to write a Router class that returns an object of the Track class. The rest does not concern us yet. Let's proceed to writing this class.

Practical Tasks

Copy the code of my Track class and place it in the file /core/Track.php.
