How to parse a Google Drive File list object

我正在使用PHP和Google Drive API，需要获得返回对象中所有文件的fileId。

下面是我的代码:

  $result = array();
        $files = array();
        $pageToken = NULL;
        try {
            $parameters = array();
            $parameters['pageToken'] = $pageToken;
            $parameters['q'] = "trashed=false and title contains '".$folderName."'";
            $files = $this->service->files->listFiles($parameters);            
            $result = array_merge($result, $files->getItems());            
            $pageToken = $files->getNextPageToken();
        } catch (Exception $e) {
            print "An error occurred: " . $e->getMessage();
            $pageToken = NULL;
        }
        print_r($result);

如何获得$result变量中所有文件的fileId ?

Just do:

foreach($files->items as $item)
{
   echo $item['id'];
}
