php question--stripping out non letters...

I was wondering if there's an easy way to strip out all
characters out
of a string that are not letters or numbers?

Any suggestions would be appreciated...

Cheers,
Dan

or something like:

                preg_replace('/W+/','',$string)

if you also want to strip underscores:

	   preg_replace('/[W_]+/','',$string)

Actually this is what I ended up using, only without the +.
