将graphEdge转换为数组

Question

我尝试将GraphEdge转换为数组 我试试这个功能

onMessageReceived()

但似乎很清楚一些数据或我不知道..使用此功能后反应的价值为空

这里是我的代码：

$response->getGraphEdge()->asArray();

结果如果我不使用asArray（）

    $request = $this->facebook->request('GET', '/[ID_OF_MY_FAN_PAGE]/posts?fields=type,shares,reactions.limit(0).summary(true)&limit=5&since=1474473391');

    try {
      $response = $this->facebook->getClient()->sendRequest($request);
    } catch(Facebook\Exceptions\FacebookResponseException $e) {
      // When Graph returns an error
      echo 'Graph returned an error: ' . $e->getMessage();
      exit;
    } catch(Facebook\Exceptions\FacebookSDKException $e) {
      // When validation fails or other local issues
      echo 'Facebook SDK returned an error: ' . $e->getMessage();
      exit;
    }


    $posts = $response->getGraphEdge();
    $posts = $posts->asArray();

当我使用asArray（）

时的结果

array(5) {
    [0]=>
    object(Facebook\GraphNodes\GraphNode)#14 (1) {
      ["items":protected]=>
      array(4) {

是否还有其他解析getGraphEdge的解决方案？或Facebook的其他功能，以保持反应的价值？
