I’m trying to create a PHP project using MVC and routing, but I think my routes are not being appropriately understood by the server. This is my routes.php:

<?php 

function load(string $controller, string $action){

    try{
        $controllerNamespace = "app\controllers\{$controller}";

        if(!class_exists($controllerNamespace)){
            throw new Exception("O controlador {$controller} não existe!");
        }

        $controllerInstance = new $controllerNamespace();

        if(!method_exists($controllerInstance, $action)){
            throw new Exception("O método {$action} não existe no controlador {$controller}!");
        }

        $controllerInstance->$action((object)$_REQUEST);
    } catch(Exception $e){
        echo $e->getMessage();
    };

}

    $router = [
        'GET'=> [
            '/' => fn() => load('HomeController','index'),
            '/contact' => fn() => load('ContactController','index')
          ],
          'POST'=> [
            '/contact' => fn() => load('ContactController','store')
          ]  
    ];

    


?>

This is the repository, if anyone wants to see the project structure: https://github.com/pedronet00/teste_roteamento

I’ve tried to use the XAMPP server, but it did not work out as well. I’m using php -S localhost:3000 to run the project.
