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.



MySQL 5.1 PHP 5 Linux [Debian (sid)]

Regex is over-kill.

$phoneNum = preg_replace("%\D%", '', $phoneNum);//Remove everything except 

$phoneNum = ltrim($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.
