使用美元符号作为节点名称访问 PHP 对象

2022-01-19 00:00:00 json youtube-api php

我正在使用每个 PHP 的 YouTube 数据 API，并以 json 格式向特定用户请求视频供稿.json_decode 后的结果如下(简化示例):

I'm working with the YouTube Data API per PHP and requesting a video feed from a specific user in json-format. The result after json_decode is the following (shortened example):

stdClass Object
(
    [version] => 1.0
    [encoding] => UTF-8
    [feed] => stdClass Object
        (
            [xmlns] => http://www.w3.org/2005/Atom
            [xmlns$media] => http://search.yahoo.com/mrss/
            [xmlns$openSearch] => http://a9.com/-/spec/opensearchrss/1.0/
            [xmlns$gd] => http://schemas.google.com/g/2005
            [xmlns$yt] => http://gdata.youtube.com/schemas/2007
    )
)

我的问题是:如何使用 PHP 访问例如节点xmlns$media"?在美元符号内它不起作用还是有一种我还没有得到的方法?

My question is: how can I access for example the node "xmlns$media" with PHP? Within the dollar-sign it won't work or is there a way which I didn't get yet?

推荐答案

这将起作用:

echo $object->feed->{'xmlns$media'};

或者，您可以告诉 json_decode 返回一个数组:

Alternatively, you can tell json_decode to return an array:

$array = json_decode($json, true);
echo $array['feed']['xmlns$media'];
