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. Ethan MySQL 5.1 PHP 5 Linux [Debian (sid)]

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");
    }
