Question

这是我第一次使用网络服务。我的PHP服务器从.net服务器获取json数据，并将其编码为base64。

现在的问题是，我无法读取数据中的每个属性：

我曾尝试使用Object，Array或json获取数据但总是失败。

//$json = json_decode($data, true); //array
//$json = json_decode($data); //object
//echo $result; //JSONDataResult

以下是FAILED方法之一。完整的流程编码：

        curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
        curl_setopt($curl, curlopt_httpheader, array ("Content-type:application/json"));

        $result = curl_exec($curl);
        curl_close($curl);

伙计们帮助我阅读内容。我不介意使用哪种方法，只要我能读取内容中的每一列。很多人，谢谢。
