According to the Zend Framework API Documentation you are getting a SimpleXML object. You can read an attribute of a SimpleXMLElement with it's attributes() method:

根据Zend Framework API文档,您将获得一个SimpleXML对象。您可以使用它的attributes()方法读取SimpleXMLElement的属性:

$track->attributes()->nowplaying

You can give these a try:

你可以试试这些:

$track['nowplaying']

or:

$track->getAttrib('nowplaying')

or:

$attributes = $track->attributes();
echo $attributes['nowplaying']

I don't see it in the docs anywhere though.

我没有在任何地方的文档中看到它。

Not really knowing much about this subject (except for the Audioscrobbler protocol), googling for it seems to indicate that $track->getAttribute("nowplaying") should do the trick. HTH.

对于这个主题并不是很了解(除了Audioscrobbler协议),谷歌搜索似乎表明$ track-> getAttribute(“nowplaying”)应该可以解决问题。 HTH。
