I already have php header files created for my site which I'd like to also use in the UCCASS system. However, when I try to include the PHP header files into the TPL files, I just get Smarty template errors. Is there a way of using existing PHP headers within the UCCASS without copying/pasting (and in essence creating a duplicate of the header file) the text into the TPL files?

I found it ... instead of including the php with traditional
<? php stuff ?>

I used
{php} php stuff {/php}

and it works great! Found this in the Smarty Wiki.
