Are there best practices for tracking and monitoring active sessions in PHP?

To track and monitor active sessions in PHP, one best practice is to store session data in a database rather than relying solely on PHP's default session handling. This allows for more control over session management and easier tracking of active sessions.

// Start the session
session_start();

// Set session save handler to store session data in a database
// Replace 'db_host', 'db_username', 'db_password', and 'db_name' with your database credentials
$mysqli = new mysqli('db_host', 'db_username', 'db_password', 'db_name');
$handler = new mysqliSessionHandler($mysqli);
session_set_save_handler($handler, true);

// Register session handler
register_shutdown_function('session_write_close');

// Check if session is active
if (isset($_SESSION['user_id'])) {
    // Do something with the active session
}
