I use preg_match to validate the Middle Initial field of a form and so far
it works, except yesterday a user submitted a "0" (zero) as a middle
initial! My regexp is:
if (!empty($_POST[MI]) && (preg_match('/^[[:alpha:]]{1,1}$/', $_POST[MI]) == 0))
I tested it with 0-9 and my regexp catches every digit except 0. Curious...
