I'd be tempted to go with eval - or alternatively perhaps you can use
something like 'bc' which /might/ allow you users to enter nasty
characters without the same fear of exploitation, but it's unlikely.

(Nothing on pecl.php.net that seems to jump out at me as being of use.)
(http://uk2.php.net/bc seems to be of limited use)
