In your case the router.php was executed with no r GET param, causing the notice. You can duplicate that by accessing: http://127.0.0.1:8000/test.php (notice the r GET param is not set). As a good practice you should always use isset() before trying to access a param that might not be set: if (isset($_GET['r'])) { // use it }
