All of your effort is very appreciated, Matt. I'm grateful for the
time you have put into this, but I think I have figured it out.

Apparently, $_SERVER does not like the use of a http web file path
when doing an include. I had been using http://jalanjones.com/...
to specify the path to the file. For the heck of it, just to try
anything, I changed the path to the local file system syntax,
'includes/index_ body.php', and it now works as it should.

I'm using...

if ($_SERVER['PHP_SELF'] == '/index.php'){include('signature.php');}

....without any errors. If I change 'index' to anything else, for
example 'index_2', it does not include the signature or give an
error. The short script is page specific and can be used, with
modified paths, in any file. That's just my speed; keep it simple
for stupid. :) I have a lot of learning to do and you helped me get
over this hump, thank you.
