PHP Failure Inside An MS Office Generated Webpage

Greetings Experts,

I have a problem with getting php to work inside a document that was auto-generated by MS Office (Outlook to be precise).  I had some code I wanted to put into the poppersinversion.org newsletter.  The newsletter is created in stages, one of which is normally to save an Outlook message to an html file.  This time, I decided to put some code in the page.  My Linux web host supports php, and I had previously had the code written and tested, but when put in the newsletter page it did not work.  In fact NO php code works inside the Office generated page.   You can see for yourself at http://www.poppersinversion.org/pos/2015/pos-2015-q3.php .  Look at the page source and search for the variable $report.  You can literally see the php code!  I suspect this has something to do with all the schemas that were loaded, but then which one and is it necessary?  Or is it something else?

Thanks,
NCM
