How does the expiration of cookies affect PHP session persistence?

When cookies expire, the PHP session data stored in them will no longer be accessible, leading to session data loss and potentially disrupting the user's experience on the website. To ensure PHP session persistence even after cookie expiration, you can configure PHP to store session data on the server rather than relying on cookies.

// Set session save path to store session data on the server
session_save_path('/path/to/session/directory');
// Start the session
session_start();
