[PHP] regular expressions and Phone validation

Hi all, I have one small problem I don't understand the preg_replace() method. I understand the gist of what it does but I still don't fully know what it does. I have read the entry in the php manual about this and I am still confused about it. I've never been any good with regular expressions.
