好的，所以我调用了 Twitter API 来返回我朋友的状态，我做了一个 var_dump，它返回了一个信息数组.. 但是，我只想捕捉我朋友的 PROFILE IMAGEs .. 所以这就是我为抓住它所做的，它没有返回任何东西

$friends = $connection->get('statuses/friends_timeline'); //method that catches my friends'statuses on Twitter.
var_dump($friends);

下面的循环应该显示我朋友的图像..循环下面是var_dump返回给我的示例..我哪里出错了？？？

if( is_array($friends))
{
    shuffle($friends);
}              

for($i=0; $i <=count($friends);$i++)
    if (is_array($friends))
    {
         foreach ($friends[$i] as $key => $value)
         {                                     
             if(array_key_exists("profile_image_url", $friends[$i]))
             {                                   
                 echo "<img src='". $value."' width='100' height='100'/>";
             }

         } 
    }

看起来像＃8，但我可能算错了。

请允许我解释。上面的代码将在 Var Dump 下的浏览器窗口中输出 6 个键。数组包含键值对，因此要查看您想要的类型 $arrayname[#];

所以 id_str 将是 $friends[5]。

将其打印到您的浏览器将使其清楚，但就像我说的那样。希望这可以帮助。

编辑。我这样打字，这正是我做事的方式。它也属于言论自由法。如果您无法清楚地阅读此内容，则此页面上可以选择发布您自己的答案。如果我花时间和精力输入任何内容。我希望它保持我输入的方式。我会根据需要继续修复它。

无所事事但批评他人做事方式的人需要获得生活。我和这个网站上的大多数其他人一样，是一名程序员，我会抽出时间来帮助其他人解决我多年前或今天遇到的问题。

我也花时间跟进这个对我来说似乎很难的人。我很快发现事实并非如此。他只是每个人的迪克。

所以，如果我这样输入。或者如果像这样输入。甚至像这样。我仍然明白我的意思。

另外，查尔斯，你是我见过的第一个对我的打字方式发表意见的人。除了我的 Shift 键受到打击，不是你。事实上，没有查尔斯在创建此消息时受到伤害。

有想要帮助的程序员。然后是那些在那儿工作了几年的人，他们认为他们什么都知道，并且想把所有他们认为比他们小的人都当作垃圾对待。请大家关注他的帖子，看看你得出什么结论。
