如何在php中回显xml文件

Question

How to print an xml file to the screen in php?

This is not working:

$curl = curl_init();        
curl_setopt ($curl, CURLOPT_URL, 'http://rss.news.yahoo.com/rss/topstories');   
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);   
$result = curl_exec ($curl);   
curl_close ($curl);    
$xml = simplexml_load_string($result);
echo $xml;

Is there a simple solution? Maybe without SimpleXML?

You can use HTTP URLs as if they were local files, thanks to PHP's wrappers

You can get the contents from an URL via file_get_contents() and then echo it, or even read it directly using readfile()

$file = file_get_contents('http://example.com/rss');
echo $file;

or

readfile('http://example.com/rss');

Don't forget to set the correct MIME type before outputing anything, though.

header('Content-type: text/xml');
