I'm trying to strip the hyphens out of a posted phone number field so that I can re-format them uniformly whether the user uses hyphens or not. I've used trim() before without much trouble but for some reason it's not stripping out the characters.

CODE

    function formatPhone($ph){
        $trimmed = trim($ph, "-");
        $phA = substr($trimmed, 0, 3);
        $phB = substr($trimmed, 3, 3);
        $phC = substr($trimmed, 6);
        return $phA."-".$phB."-".$phC;
    }
    
    $phone = formatPhone($_POST['phone']);
    $contact_phone = formatPhone($_POST['contact_phone']);

Why don't you just use str_replace and do something like:

CODE
str_replace("-", "", $thephonenumber

It'll replace the hyphen with nothing, in other words, it'll get rid of the hyphens.

That did the trick, thanks!
