Wouldn't it be easyer if php would just putt it also in the var $1 wich you
can pass to the function?

btw if i would fist escape the ' an " in a preg_replace i wouldn't need the
second to do an addslashes on it :)

but the addslashes was just for the example.. and to give you some stuff to
thing about the e option in preg_repace
