Removing Unwanted Characters Using ereg_replace

Please tell me how i can remove a series of characters using ereg_replace.

So far, i've been successful in removing one character only using this:

$string = ereg_replace('\"', '', $string);

What should i add so i could remove all characters and just retain the letters and numbers only?

thnks!

got it already:

$string = ereg_replace("[^a-zA-Z0-9\s ]", '', $string);

Good.

Looks like you have started to learn man :)

you know me, always giving myself problems to solve.

That's the attitude I like :)
