UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support apache variable in header?

I´m trying to introduce a new layout which contains some dynamic elements, which switch atrributes like color / navigation elements, depending on in which section you currently are.
I´m using the apache variable $SCRIPT_FILENAME.

But, somehow this won´t work in the header of UBBT.
simple example:
<?php echo $SCRIPT_FILENAME; ?>

This won´t execute. I have plenty of php code in header and footer, but somehow this won´t work.
Any idea why?
thanks!

Try $_SERVER['SCRIPT_FILENAME']

respectively

<?php echo "{$_SERVER['SCRIPT_FILENAME']}"; ?>

it worked, great, thanks!
