你确定self:：substr吗？应该是这样的：

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);
}
