If you'll remember a while back, we posted something from DevArticles about creating a RSS feed for your site. Well, here with the other side of that coin is Zend with an article by Matt Wade - Displaying an RSS feed with PHP.

In this piece, Matt discusses the retrieval, parsing and display of a remote RSS file for use in your site. He starts off with a brief description of what RSS is and how it can help you, then moves right into the code, helping you create some functions (that might live well in a class with a little adjustment) to do all the hard work for you. It just uses the built-in expat functions of PHP, so you probably won't need to compile anything extra in (unless you're using an older version of PHP).
