In what scenarios would using a database-based session be more advantageous than a regular session in PHP?

Using a database-based session in PHP can be more advantageous than a regular session when dealing with large amounts of session data or when needing to share session data across multiple servers in a clustered environment. By storing session data in a database, you can easily scale your application without worrying about session data loss or inconsistency. 

// Enable database-based sessions in PHP
ini_set('session.save_handler', 'user');
ini_set('session.save_path', 'tcp://localhost:3306?persistent=1&dbname=session_db');

// Start the session
session_start();

// Use session variables as usual
$_SESSION['user_id'] = 123;
