How can PHP scripts be optimized for better session handling?

To optimize PHP scripts for better session handling, it is important to minimize the amount of data stored in sessions, avoid storing sensitive information, and periodically clean up expired sessions to prevent performance issues. 

// Set session.gc_maxlifetime to a lower value to clean up expired sessions more frequently
ini_set('session.gc_maxlifetime', 3600); // 1 hour

// Limit the amount of data stored in sessions
$_SESSION['user_id'] = 123;

// Avoid storing sensitive information in sessions
unset($_SESSION['password']);
