How Do I Automate Website Updates with RSS?

A friend of mine informed me of a PHP script that you have to automate RSS feed updates.  You then can insert the feed using a template into a page. The feed will dynamically update on the page, but search engines see the contents as static.    If you have, or can send me a link to, this script, that would be great.

rss2html.php is a free PHP script that can be used to dynamically update the contents of a webpage. Each time the RSS feed is updated the webpage will dynamically update.
