Php retrieveAllFiles函数的参数

我正在尝试使用google drive API函数retrieveAllFiles（）显示google drive帐户中的文件列表， 但由于它的参数，我不知道如何调用它。这里是函数

      function retrieveAllFiles($service) {
      $result = array();
      $pageToken = NULL;

      do {
        try {
          $parameters = array();
          if ($pageToken) {
            $parameters['pageToken'] = $pageToken;
          }
          $files = $service->files->listFiles($parameters);

          $result = array_merge($result, $files->getItems());
          $pageToken = $files->getNextPageToken();
          print $pageToken;
        } catch (Exception $e) {
          print "An error occurred: " . $e->getMessage();
          $pageToken = NULL;
        }
      } while ($pageToken);
      return $result;
    }
