从URL获取rss时出错？

Question

I have a sample code:

<?php 
header('Content-Type: text/html; charset=utf-8');
$doc = new DOMDocument();
$doc->load('http://www.haivl.com/rss');

$items = $doc->getElementsByTagName('item');
foreach ($items as $key => $item) {
    $titles = $item->getElementsByTagName( "title" );
    $title = $titles->item(0)->nodeValue;
    echo $title;
}
?>

I can't get title from this url, why error, can help me fix this error !

Answer 1

The problem is these two lines

$title = $titles->item(0)->nodeValue;
echo $titles;

You're assigning the title value to $title but echoing $titles. $titles is a DOMNodeList and can't be converted to a string implicitly. You want to do

$title = $titles->item(0)->nodeValue;
echo $title;
