Parameters

$status: Disables writing of session data when FALSE, (re-)enables writing when TRUE.

Return value

FALSE if writing session data has been disabled. Otherwise, TRUE.

Code

function drupal_save_session($status = NULL) {

  // PHP session ID, session, and cookie handling happens in the global scope.

  // potentially wrong or disallowed session would be written otherwise.
  static $save_session = TRUE;
