处理 post 个附件 Facebook API SDK 4

Question

朋友，我无法处理return调用的数据。我如何与数据交互，特别是与附件交互。调用此链接的完整结果：http://pastebin.com/fLjV0Zu2

我正在使用数组的转换方法，但似乎此方法不会在对象的所有级别进行交互。所以我无法到达要处理的数据附件。

$graphObject = $response->getGraphObject()->asArray();

$media = $graphObject->getProperty('attachments')->asArray();
print_r($media);

结果：

Array
(
[0] => stdClass Object
    (
        [subattachments] => stdClass Object
            (
                [data] => Array
                    (
                        [0] => stdClass Object
                            (
                                [media] => stdClass Object
                                    (

对于有同样问题的人。或者更确切地说是怀疑。

朋友WizKid扫清了我的思路

即使使用正确的方法使用Facebook PHP SDK4 转换GraphObject 的结果，调用asArray(); 来访问数据，我使用下面的表格也成功了。

$media = $graphObject->getProperty('attachments')->asArray();
$media[0]->subattachments->data;

与我正在使用的数据进行交互 foreach()

$data = $media[0]->subattachments->data;
    foreach($data as $k => $v) {
      //Here you interacted with the data
    }
