[Zope] Serve PHP/Perl within Zope

[sharif islam]

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.
