Email validity check
PHP code:
function is_email($email){ $x = '\d\w!\#\$%&\'*+\-/=?\^_`{|}~'; //just for clarity
return count($email = explode('@', $email, 3)) == 2 && strlen($email[0]) < 65 && strlen($email[1]) < 256 && preg_match("#^[$x]+(\.?([$x]+\.)*[$x]+)?$#", $email[0]) && preg_match('#^(([a-z0-9]+-*)?[a-z0-9]+\.)+[a-z]{2,6}.?$#', $email[1]);}
