RE: [PHP] Phone number validation

I do this for phone numbers: $row['mobile'] = ereg_replace("[^0-9]", '', $_POST['mobile']); if ((strlen($phone)) <= 14) return preg_replace ("/[^0-9]*([0-9]{3})[^0-9]*([0-9]{3})[^0-9]*([0-9]{4}).*/", "(\\1) \\2-\\3", $phone); > Is it possible for anyone to tell me what php method is used to grab > the first charater of a string?
