How can PHP sessions be effectively managed to update user status when the session expires or is closed?

When a PHP session expires or is closed, the user status needs to be updated to reflect this change. One way to achieve this is by using session callbacks to trigger an update function when the session expires. This function can update the user status in the database or perform any necessary actions. 

// Set session callback to trigger function when session expires
session_set_save_handler(
    function ($savePath, $sessionName) {
        // Set custom session save handler
    },
    function () {
        // Function to update user status when session expires
        // Update user status in the database or perform necessary actions
    },
    function ($sessionId) {
        // Function to destroy session
    },
    function ($maxLifetime) {
        // Function to clean up expired sessions
    }
);

// Start the session
session_start();
