[Zope] How to serve php from within Zope

Hi, I'm using Apache to serve my Zope pages. I want to serve up some PHP scripts as part of a page wrapped with Zope methods. How do I serve the contents in the /some/other/directory/for/PHP/scripts from within Zope? For example, I want to call index.php3 from within the index_html of a Zope folder and have the contents included in the place I make the call. Andres Corrada
