php - 如何解码来自 facebook 的 Json 响应

Question

我已经使用 $my_friends = json_decode(file_get_contents($frens)); 和 print_r($my_friends); 解码了来自 facebook 的 JSON 响应，给出了以下响应:

    stdClass Object
(
    [data] => Array
        (
            [0] => stdClass Object
                (
                    [name] => Mrinal Kumar Rai Baruah
                    [id] => 546111977
                )

            [1] => stdClass Object
                (
                    [name] => Roshan Khangembam
                    [id] => 553139665
                )

            [2] => stdClass Object
                (
                    [name] => Tarunesh Kumar Saurav
                    [id] => 620690126
                )
.........................
        )

)

我是 JSON 的新手，我很困惑。我如何迭代上述响应以获取名称？

foreach($my_friends['data'] as $key => $val) {
   echo "Friend #{$key} = {$val['name']}\n";
}
