由于我偶然发现了一些错误的解决方案（至少总是指向正确的方向）将你的 instagram 照片拉到我的网站上，我开始寻找新的方法。而且我必须在 cURL 脚本部分中实现 SSL 才能获得 instagram 提要。

但是我被困在以下部分：如何告诉我的脚本显示我的图像？

我发现，这$result->data行得通，但如果我继续使用 PHP 这行->images代码会给我"Trying to get property of non-object". 并且解码后的 JSON 的输出仍然缺乏概览性。我在这里粘贴了我现在的代码，调试模式。

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.instagram.com/v1/users/myUserID/media/recent/?access_token=myAccessToken');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 20);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
$result = curl_exec($ch);
curl_close($ch); 

$result=json_decode($result);
$data=($result->data);
var_dump ($data->images);

// echo "<img src="$result->images->thumbnail->url">"
?>

这是的输出json_decode：

  }

我的目标是在我的网站上只有一张图片，但导航箭头可以切换到下一张。那将如何实现？

要从 StdClass 访问信息，您可以这样做：

foreach($data->images as $i){
   $i->url;
}

您也可以强制强制转换为数组：

foreach($data->images as $i){
   $i = $i->toArray();
   $i['url'];
}

你可以得到数组形式的 json 解码：

$data = json_decode($json,true); //the second param true means, bring me it like array.

根据http://php.net/json_decode，您需要指定您想要一个关联数组而不是来自 json_decode 的对象：

所以像这样使用json解码

$result=json_decode($result, true);

现在您将获得数组，您可以轻松访问数据。
