I did it once in my Framework before switching to Laravel.

We still use My Framework for mission critical systems.

You need to do the following:

1. Create a Router class that will handle mapping routes to their respective controller methods.

   class Router {
       protected $routes = [];
   
       public function addRoute($method, $uri, $controller, $action) {
           $this->routes[] = [
               'method' => $method,
               'uri' => $uri,
               'controller' => $controller,
               'action' => $action
           ];
       }
   
       public function getRoute($method, $uri) {
           foreach ($this->routes as $route) {
               if ($route['method'] === $method && $route['uri'] === $uri) {
                   return $route;
               }
           }
           return null;
       }
   }
   
   

2. Define Your Controller.

   class UserController {
       public function create() {
           echo "Creating a new user!";
       }
   }
   
   

3. Map Routes.

   $router = new Router();

   $router-\>addRoute('GET', '/user/create', UserController::class, 'create');

You can modify the addRoute method to take array like yours.

Example:

$router = new Router();
$router->addRoute('GET', '/user/create', UserController::class, 'create');

$method = $_SERVER['REQUEST_METHOD'];
$uri = $_SERVER['REQUEST_URI'];

$route = $router->getRoute($method, $uri);

if ($route) {
    $controller = new $route['controller']();
    $action = $route['action'];
    $controller->$action();
} else {
    echo "Route not found.";
}

Hope this will help you.
