我用 giggsey/libphonenumber-for-php 为此：

public function rules(): array
    {
        return [
    '*.sender_phone_code' => ['required', 'integer', 'digits:3'],
    '*.sender_phone_number'   => ['required', 'integer', 'digits:9', function ($attribute, $value, $fail) {
            $phoneUtil = \libphonenumber\PhoneNumberUtil::getInstance();
            try {
                $phoneNumberProto = $phoneUtil->parse($value);
            } catch (\libphonenumber\NumberParseException $e) {
                $fail('The '.$attribute.' is invalid.');
            }
            if (!$phoneUtil->isValidNumber($phoneNumberProto)) {
                $fail('The '.$attribute.' is invalid.');
            }
        }]
]}
