If session cookie lifetime is 0  the session cookie lives until the browser is quit   EDIT  Others have mentioned the session gc maxlifetime setting  When session garbage collection occurs  the garbage collector will delete any session data that has not been accessed in longer than session gc maxlifetime seconds  To set the time-to-live for the session cookie  call session set cookie params   or define the session cookie lifetime PHP setting  If this setting is greater than  session gc maxlifetime  you should increase session gc maxlifetime to a value greater than or equal to the cookie lifetime to ensure that your sessions won t expire

In general you can say session gc maxlifetime specifies the maximum lifetime since the last change of your session data  not the last time session start was called    But PHP   s session handling is a little bit more complicated   Because the session data is removed by a garbage collector that is only called by session start with a probability of session gc probability devided by session gc divisor  The default values are 1 and 100  so the garbage collector is only started in only 1  of all session start calls  That means even if the the session is already timed out in theory  the session data had been changed more than session gc maxlifetime seconds ago   the session data can be used longer than that   Because of that fact I recommend you to implement your own session timeout mechanism  See my answer to How do I expire a PHP session after 30 minutes  for more details
