How to make a simple php router (router)?

Question

PHP

Please tell me a ready-made example of a simple router. And if possible, describe the principle of operation

Answer 1

Well, right on the matches:

/* index.php */
$controllerClass = ucfirst($_GET['controller']);
$method = $_GET['method'];

require_once("controllers/$controllerClass.php");
$controller = new $controllerClass();
$controller->$method();

(no error checking or protection, of course).
Handles a url like /index.php?controller=user&action=edit
Creates a User class object (from controllers/User.php) and calls the edit() method
