I don't think you really need restrictedTraverse here, but can let
acquisition do the job::

<dtml-var "Plone.reports.Site2.myObject">

should work fine. Even better::

<span tal:replace="structure context/Plone/reports/Site2/myObject" />

But that's just because I push ZPT.

The basic problem you have above seems to be that the basic "call"
behaviour of the PHP document object is to hand over its source, and not
to render itself, which is strange. (Can you just visit that URL and see
it rendered?) You may be able to get it to do that by tacking an
'index_html' at the end. Otherwise you'll have to investigate the
API/source of that object to see what method makes it render itself. I
don't know anything about it, so I can't tell you off-hand. (You may be
able to find this out based on the URL of the "view" tab in the ZMI.)
