_drupal_session_garbage_collection($lifetime)

Cleans up stalled sessions.
Parameters
$lifetime: The value of session.gc_maxlifetime, passed by PHP. Sessions not updated for more than $lifetime seconds will be removed.
File
- includes/session.inc, line 499
- User session handling functions.
Code
function _drupal_session_garbage_collection($lifetime) { // Be sure to adjust 'php_value session.gc_maxlifetime' to a large enough // value. For example, if you want user sessions to stay in your database // for three weeks before deleting them, you need to set gc_maxlifetime // to '1814400'. At that value, only after a user doesn't log in after // three weeks (1814400 seconds) will his/her session be removed. db_delete('sessions') ->condition('timestamp', REQUEST_TIME - $lifetime, '<') ->execute(); return TRUE; }
