use Symfony\Component\HttpFoundation\Response; // Check if user is authenticated if (!$userIsAuthenticated) { $response = new Response(); // Redirect to login page $response->headers->set('Location', '/login.php'); $response->send(); exit; } else { // Redirect to sensitive data page $response = new Response(); $response->headers->set('Location', '/sensitive-data.php'); $response->send(); exit; }In this example, the code uses the Symfony HTTPFoundation component to create a new HTTP response object and set the location header to the appropriate page. If the user is authenticated, they will be redirected to the sensitive data page. If not, they will be redirected to the login page.
