Re: Formatting phone numbers

preg_replace will do it. $returnValue = preg_replace("/(\d{3})(\d{3})(\d{4})/","($1)$2-$3",$returnValue); (\d{3})(\d{3})(\d{4}) = $0 or \\0 we aren't using this match we are using the subpatterns in brackets (\d{3}) =$1 or \\1 matches 3 numbers (\d{3}) =$2 or \\2 matches 3 numbers (\d{4}) =$3 or \\3 matches 4 numbers which we use to make the replacement ($1)$2-$3 http://za2.php.net/manual/en/function.preg-replace.php so that's the phone number, I'll leave the cc to you.

What I have below will currently remove non-numeric characters from the string, but I'm not sure how to do the rest of the formatting. Any help would be appreciated. By the way, any recommendations for good php tutorials for beginners?
