CodePudding user response：

Are you sure with the self::substr ? It should be this :

public function valid_email($email) {
        if (function_exists('idn_to_ascii') && defined('INTL_IDNA_VARIANT_UTS46') && $atpos = strpos($email, '@')) {
            $email = substr($email, 0,   $atpos) . idn_to_ascii(substr($email, $atpos), 0, INTL_IDNA_VARIANT_UTS46);
        }
        return (bool) filter_var($email, FILTER_VALIDATE_EMAIL);
    }
