How can PHP be used to automatically delete guest user data after a certain period of inactivity, and what considerations should be taken into account when implementing this feature?

To automatically delete guest user data after a certain period of inactivity in PHP, you can set a timestamp for each user's last activity and check it against the current time to determine if the data should be deleted. Considerations should include defining the period of inactivity, implementing a mechanism to regularly check and delete inactive data, and ensuring proper validation and security measures are in place. 

// Set the period of inactivity (e.g. 30 minutes)
$inactivePeriod = 30 * 60; // 30 minutes in seconds

// Check and delete inactive guest user data
if(isset($_SESSION['last_activity']) && (time() - $_SESSION['last_activity'] > $inactivePeriod)) {
    // Delete guest user data
    unset($_SESSION['guest_user_data']);
}

// Update last activity timestamp
$_SESSION['last_activity'] = time();
