public function valid_email($email) {
if (function_exists('idn_to_ascii') && defined('INTL_IDNA_VARIANT_UTS46') && $atpos = strpos($email, '@')) {
$email = self::substr($email, 0, $atpos) . idn_to_ascii(self::substr($email, $atpos), 0, INTL_IDNA_VARIANT_UTS46);
}
return (bool) filter_var($email, FILTER_VALIDATE_EMAIL);
}
請幫忙
uj5u.com熱心網友回復：
您確定使用 self::substr 嗎？應該是這樣的：
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);
}
