if ($open_basedir) {
  $requirements['php_open_basedir']['severity'] = REQUIREMENT_ERROR;
  $requirements['php_open_basedir']['description'] = $t('The testing framework requires the PHP open_basedir restriction to be disabled. Check your webserver configuration or contact your web host.', array('@open_basedir-url' => 'http://php.net/manual/en/ini.core.php#ini.open-basedir'));
  }
