我的英语水平很差。如果我犯了错误，我很抱歉。我正在尝试通过 php 连接抽搐 api，但出现错误。
<?php
$json=@json_decode(file_get_contents("https://api.twitch.tv/kraken/streams/artemis"));
$json->display_Name;
?>请帮帮我，谢谢。
您需要向下潜入响应树。您要查找的属性位于流>通道中。要得到它，只需做
echo $json->stream->channel->display_name
这应该有效：
$json=json_decode(file_get_contents("https://api.twitch.tv/kraken/streams/artemis"));
$json->stream->channel->display_name;
检查$json它是对象的对象的var_dump：
