php / curl / xml parser

Question

a while ago i did a quick news parser for a friend.

here is the code:

$ch = curl_init("http://feeds.energydigger.com/headlines.xml");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$data = curl_exec($ch);
curl_close($ch);
$doc = new SimpleXmlElement($data, LIBXML_NOCDATA);

if(isset($doc->channel))
{
    parseRSS($doc);
}
function parseRSS($xml)
{
    $cnt = 3;
    for($i=0; $i<$cnt; $i++)
    {
    $url    = $xml->channel->item[$i]->link;
    $title  = $xml->channel->item[$i]->title;
    $desc = $xml->channel->item[$i]->description;
    $date = $xml->channel->item[$i]->pubDate;

    echo '<p><a href="'.$url.'">'.$title.'</a><br />'.$date.'</p>';
    }
}

this has been working perfect up till today and now i am getting a 500 server error on the page its trying to show the list.

Have i missed something obvious here or that anyone can spot easily

thanks in advance

PS i modified someones code i found a tutorial on

What exact 500 error do you get? Besides this: "PS i modified someones code i found a tutorial on" - that's not a good thing, try something on your own and the search for errors is even easier :-) — akluth

A 500 status code (or a blank page) means that your script is throwing an error but you haven't configured PHP to display error messages. That's something you need to fix before you go further; it's impossible to code without the aid of error messages. Here's a brief explanation. — Álvaro González

I just copy and pasted you code in a php page on my server and it works correctly.

I suspect your problem is curl installation. You probably get this error: Fatal error: Call to undefined function curl_init() on line 2 This is because you need to initialize curl extension.

Here is how to do it: http://nz.php.net/manual/en/curl.installation.php

This might also help:

Call to undefined function curl_init()

curl_init() function not working
