What role do push notifications play in maintaining user sessions in PHP applications like autologin systems?

Push notifications can play a crucial role in maintaining user sessions in PHP applications like autologin systems by alerting users when their session is about to expire or when they need to reauthenticate. This can help prevent sessions from timing out unexpectedly and provide a seamless user experience.

// Example code snippet for sending a push notification to remind users to reauthenticate
$userId = $_SESSION['user_id'];
$message = "Your session is about to expire. Please reauthenticate to continue.";
$pushNotificationService = new PushNotificationService();
$pushNotificationService->sendNotification($userId, $message);
