The fastest way to replace a sequence of characters in a string

Question

I am wondering what is the fastest way to replace some characters in a string with nothing. Now I have the following:

$omschrijving = str_replace(")", "", str_replace("(", "", $line)));

Is there a better way to do this? This replaces only "("and ")", but what if I want to do the same with a lot of characters. Still learning the methods preg_, but at the moment still a little bloated.
