// Get the requested page URL $page = getRequestedPage(); // Redirect the user to the login page if they are not logged in if (!isLoggedIn() && $page != '/login') { header('Location: /login'); exit; }
// Get the requested page URL $page = getRequestedPage(); // Load the appropriate controller based on the requested page switch ($page) { case '/home': $controller = new HomeController(); break; case '/about': $controller = new AboutController(); break; case '/contact': $controller = new ContactController(); break; default: $controller = new ErrorController(); } // Execute the controller's action $controller->execute();In this example, the getRequestedPage function is used to determine which controller to load based on the requested page. This is a common pattern in MVC (Model-View-Controller) frameworks, which use controllers to handle requests and generate responses. The package used to implement the getRequestedPage function is not clear from the examples provided, as it could be part of a custom library or a built-in PHP function. However, similar functionality can be found in many web development frameworks and libraries.
