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

so that's the phone number, I'll leave the cc to you.

Subject: [PHP] Formatting phone numbers
Hi,
I'd like to write a function that will take a string of characters and
output it in a phone number format (xxx)xxx-xxxx and one for credit
cards xxxx-xxxx-xxxx-xxxx. 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?
Thanks,
Corinne
