According to the comment by @Gerben ...
Adding <!-- does not work. The host is already launching its additional commentary, and the --> that follows it is redefined.
Adding header('Content-Type: text/xml'); Does nothing, javascript still shows.
BUT! We found the answer ... put exit(); at the end of the PHP script will disable this feature!
As a note to Mr. @ Herben - Thank you, and I voted for one of your other answers, so you will get a loan for this ...
