Let me make sure I understand your question corectly. You have an RSS feed and you want to syndicate this feed on your PHP-driven site?

What you will need is a PHP-based RSS parser. A relaly good, and really powerful one, that I love is called MagpieRSS - http://magpierss.sourceforge.net

It has lots of options but don't let that overwhelm you. Read the FAQ and you will see that it only takes a couple of lines and for you to upload the magpierss folder.

Here is a very basic example:

[php]
require_once('magpierss/rss_fetch.inc');
$url = "path/to/rss/feed.rss";
$rss = fetch_rss($url);
echo "<ul>";
foreach ($rss->items AS $item)
{
$title = $item['title'];
$link = $item['link'];
echo "<li><a href=\"$link\">$title</a></li>";
}
echo "</ul>";
?>
[/php]
