You should really put a doctype here:

<!DOCTYPE html>

> <HTML>

at the top of your html so that the browser doesn't operate in quirks
mode (q.v.).

This ...

.... and this are surely no-ops as you don't assign the output of
stripslashes (q.v.) to anything.

The include is *always* processed by PHP - see:

Well, include might do it, I suppose. On first reading of the include
ref I gave above, I assumed that include's argument had always to be a
specific file, but there seem to be some hints in the user examples
that imply you could do:

include $filenamer;

instead of

print $text;

but I've never tried this myself.

BTW I've read that google etc ignore <meta keywords...> these days but
that's another story.
