我正在尝试使用 soundcloud API 并尝试从我的 JSON 对象中提取所有播放列表标题，以制作一个带有引用的列表。实际上我对 JSON 没有太多经验，因此我无法从解码的 JSON 数组中调用任何变量......

http://api.soundcloud.com/users/55607614/playlists.json?client_id=YOUR_CLIENT_ID

我已经通过http://jsonviewer.stack.hu/查看了结构，但它并没有真正帮助我......

$json = json_decode(file_get_contents("http://api.soundcloud.com/users/55607614/playlists.json?client_id=YOUR_CLIENT_ID"));
echo $json[??][??]...;

有任何想法吗？谢谢！
