What is the significance of the 'session.cache_expire' setting in PHP sessions?

The 'session.cache_expire' setting in PHP sessions determines the time in seconds after which cached data will be considered stale and revalidated. Setting a lower cache expiration time can help ensure that the session data stays up to date and reduces the risk of using outdated information.

// Set session cache expiration time to 0 to disable caching
ini_set('session.cache_expire', 0);
