好吧,我真的不理解这个概念,但我不想使用小部件来远离他们的广告。
因此,我正试图从福克斯新闻为一家客户广播电台网站制作大约10个全国性的结果。我只想要一个链接,所以我需要从提要中获得标题和链接。
<?php
$xml=simplexml_load_file("http://feeds.foxnews.com/foxnews/latest");
print_r($xml);
?>
这个代码打印这个

我把它缩短了,这样更容易阅读。完整的一个在patriovoice.net上。在上面的代码中,我注意到标题是一个SimpleXMLElement对象,我曾尝试使用print_r($xml->item[0]->title);
打印它,但它什么都不打印。我做错了什么,所以我可以有10个<a href="$link">$title</a>
试试这个:
$link = $xml->channel->item[37]->link;
$title = $xml->channel->item[37]->title;
print "<a href='"$link'">$title</a>";
您必须将叶值强制转换为String。
var_dump((string)$xml->channel->item[0]->title);
没有强制转换,它们只表示空的SimpleXMLElements。
