Question

我已经将我的对象数据转换为数组，现在我试图从多维数组中提取某些部分但是我遇到了一些问题。感谢您的帮助，谢谢。

 /* PHP SDK v4.0.0 */
/* make the API call */
$request = new FacebookRequest(
  $session,
  'GET',
  '/89647580016/feed'
);
$response = $request->execute();
$graphObject = $response->getGraphObject()->AsArray();
/* handle the result */

  // print data

 echo '<pre>' . print_r( $graphObject, 1 ) . '</pre>';

以下是输出：

Array
(
    [data] => Array
        (
            [0] => stdClass Object
                (
                    [id] => 89647580016_10153019927930017

                                (
                                    [0] => stdClass Object
                                        (

                                )

如何打印所有['消息']？我试过了：

foreach ($graphObject as $key => $value) {
 echo '<br>'.$key['message'];
}

但是我收到了一个错误。谢谢你的帮助。

你的数组有一些键，其元素实际上是StdClass。您无法像$key['message']那样对其进行审核，但是：$key->message。

另外，请勿忘记包含错误消息。错误非常通用，如果没有任何错误迹象，我们无法帮助您。

我没有注意到你的foreach。由于您只在$graphObject第一级进行迭代，因此您将获得$key个数据和另一个整数数组，每个键都有一个StdClass。在foreach上，将其设为foreach ($graphObject['data'] as $key => $value)，然后将其用作echo $value->message
