只是我用
simplexml_load_file
解析xml文件
当我用它来解析文件时它工作得很好并返回所有文件内容
<?php
//$homepage = file_get_contents('');
$x = simplexml_load_file('http://www.metacafe.com/api/videos?vq=sexy&max-results=50');
echo "<pre>";
print_r($x);
echo "</pre>";
?>
输出就好了

当我尝试仅打印项目数组时问题才刚刚开始
<?php
//$homepage = file_get_contents('');
$x = simplexml_load_file('http://www.metacafe.com/api/videos?vq=sexy&max-results=50');
echo "<pre>";
print_r($x->channel->item);
echo "</pre>";
?>
这个只得到项目数组的第一个对象而不是整个数组
SimpleXMLElement Object

我需要做的是检索项目数组的整个对象
