Erm, you say regex is overkill, then use one in your example!

Dear List -
Thank you for all your help in the past.
Here is another one....
I would like to have a regex which would validate that a telephone number is
in the format xxx-xxx-xxxx.
Thanks.

Regex is over-kill.
$phoneNum = preg_replace("%\D%", '', $phoneNum);//Remove everything except
digits
$phoneNum = ltrim($phoneNum,'1');//Remove leading 1s
if(strlen($phoneValue) != 10)
{
throw new Exception("Phone number must be 10 digits, without leading a 1. Check
your entry carefull");
}
Save and use the resultant $phoneNum; It is all that needs to be saved and used.
Dashes, spaces and () are superfluous. Only the 10 digits are required for his
application.
