Question

我有一个解码的json数组，我从facebook API收到：

$Myposts = json_decode($response->getBody());

当我打印$ Myposts时：

var_dump($Myposts);

它给出了这个：

    object(stdClass)[16]
  public 'data' => 
    array (size=24)
      0 => 
        object(stdClass)[12]
          public 'message' => string 'a mesagge..' (length=65)
          public 'created_time' => string '2016-09-18T16:41:10+0000' (length=24)
          public 'id' => string '111110037' (length=35)
      1 => 
        object(stdClass)[28]
          public 'message' => string 'How brave !' (length=11)
          public 'story' => string 'XXX shared Le XX video.' (length=59)
          public 'created_time' => string '2016-09-18T13:37:33+0000' (length=24)
          public 'id' => string '102172976' (length=35)

      23 => 
        object(stdClass)[50]
          public 'message' => string '...a message..' (length=259)
          public 'story' => string 'Bi added 3 new photos.' (length=33)
          public 'created_time' => string '2015-12-11T20:54:21+0000' (length=24)
          public 'id' => string '102191588' (length=35)
  public 'paging' => 
    object(stdClass)[51]
      public 'previous' => string 'https://graph.facebook.com/v2.7/XXXX&__paging_token=YYYY&__previous=1' (length=372)
      public 'next' => string 'https://graph.facebook.com/v2.7/XXX/feed?access_token=DDDD&limit=25&until=XXX&__paging_token=XXXX' (length=362)

我是php的新手，我不知道如何处理这个输出，我想循环遍历所有消息并输出每条消息的created_time。

有什么想法吗？

编辑：我试过echo $myPosts['data'][message];来自Parsing JSON file with PHP，但我已经：＆＃34;未定义索引：消息＆＃34;。这就是我发布新问题的原因。

json_decode的第二个参数将结果转换为关联数组：

$myPosts = json_decode($response->getBody(), true);

foreach ($myPosts['data'] as $post) {
    var_dump($post['message']);
}

不使用第二个参数，解码返回对象：

$myPosts = json_decode($response->getBody());

foreach ($myPosts->data as $post) {
    var_dump($post->message);
}

在PHP中解析解码的json数组
