since the SCRIPT element is being appended to the current pae, I am not
sure that the PHP would see a new URL. The URL is just the same URL as
it was before the document.body.appendChild().
The point here is that things chane on the page without jumpin to a
new location, ie AJAX. I do not want to refresh the window.
I could look up the PHP built in variables that read the URL, but I
think thats not the right direction.

Yes, it seems Javascript would execute the output of the PHP, but you
don't use it that way. The point is to execute PHP as the result of a
page event, which it does.
After the PHP executes, you get access to the set PHP vars from
Javascript. e.g,
setTextContent( getElementById_s('divZipCheckRes'),
'<?php echo $res; ?>' );
I just wish that I could access SOMETHING in the web page from within
the PHP to get an input value. I don't know how to do that.
