How can session initialization be optimized for performance in PHP?

To optimize session initialization for performance in PHP, you can adjust the session configuration settings to reduce unnecessary overhead. This can include setting a shorter session timeout, using a more efficient session storage mechanism, and minimizing the amount of data stored in the session.

// Optimize session initialization for performance
ini_set('session.gc_maxlifetime', 3600); // Set session timeout to 1 hour
ini_set('session.save_handler', 'memcached'); // Use Memcached for session storage
session_start();
