Question

我正在使用twitter API，我试图解析json输出。但不知怎的，我做错了什么，而且我没有得到我想要的东西。

在这种情况下，我用PHP写作。开始通过数组循环并且screen_name和文本正在相应地工作。

foreach ($statuses as $obj) {

  $screen_name  =   filter_var($obj->user->screen_name, FILTER_SANITIZE_STRING);
  $text         =   filter_var($obj->text, FILTER_SANITIZE_STRING);
  $urls         =   filter_var($obj->entities->urls->url, FILTER_SANITIZE_URL);
}

JSON数组输出：

array (
  0 => 
  stdClass::__set_state(array(
     'created_at' => 'Fri Oct 07 15:31:01 +0000 2016',
     'text' => 'test',
     'entities' => 
    stdClass::__set_state(array(
       'hashtags' =>

由于urls是一个数组，因此需要对其进行索引。

$urls         =   filter_var($obj->entities->urls[0]->url, FILTER_SANITIZE_URL);

无法从解析的JSON输出中获取对象
