session.gc_maxlifetime - (default 1440 seconds) defines how long an unused PHP session will be kept alive. For example: A user logs in, browses through your application or web site, for hours, for days. No problem. As long as the time between his clicks never exceed 1440 seconds. It's a timeout value.

session.cookie_lifetime - This value (default 0, which means until the browser's next restart) defines how long (in seconds) a session cookie will live. Sounds similar to session.gc_maxlifetime, but it's a completely different approach. This value indirectly defines the "absolute" maximum lifetime of a session, whether the user is active or not. If this value is set to 6016060, every session ends after an hour.
