我如何访问此对象中的属性？ Twitter API

Question

我将此对象存储在名为results的变量中。我如何访问profile_image_url例如。

这是print_r的返回值：

  [results] => Array ( 
    [0] => stdClass Object (

Answer 1

以下是一些基本的访问示例：

//get a single profile url
echo $results->results[0]->profile_image_url;
//or
$tweet = $results->results[0];
echo $tweet->profile_image_url;

//get all the profile urls
foreach($results->results as $tweets){
  echo $tweet->profile_image_url;
}

当然，相同的基本概念适用于所有其他属性，除了（对于此特定示例数据）metadata属性，它是一个对象。

//to get result type
echo $results->results[0]->metadata->result_type;

Answer 2

试试这个：$ imageURL = $ obj-＆gt; results [0] - ＆gt; profile_image_url;

Answer 3

$object['results'][0]->profile_image_url

如果第一个对象是一个数组，那么这就是访问它的方法。

Answer 4

尝试一下它会起作用。
