User session handling functions.

Code

function sess_gc($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.
  if (variable_get('session_gc_update', 0) < time()) {
    db_query("DELETE FROM {sessions} WHERE timestamp < %d", time() - $lifetime);
    variable_set('session_gc_update', time() + 300);
  }
  return TRUE;
}
