[Zope] Serve PHP/Perl within Zope

Has anyone tried using this method: http://www.zope.org/Members/Mamey/PHP I am little confused about how to serve the actual php content within the files. I added file with this: <dtml-if "REQUEST.has_key('phpScript')"> <dtml-var "ServePHPContent(REQUEST['phpScript'])"> </dtml-if> Then I tried to begin the php content after this and saved it as file.php3. However, when I view zope doesn't render it. --Sharif
