Im having some dificulty finding out weather or not it is actualy possible to use php as a rewritemap prg: script - as this forum is the mod_rewrite forum, i guess you guys are prob the best people to ask

I have spent ages looking and can seem to find a definitive answer?
This bloke seems to think you can in one of his examples

But i cant find any other information on the matter?
Has anyone had any experence with this?
Thanks in advance
