提问by Adam Kozlowski
Is it possible to use Laravel Language Translator (Localization) in controller as constant? Below attempt, example that does not work:
是否可以在控制器中使用 Laravel 语言翻译器（本地化）作为常量？下面的尝试，不起作用的例子：
class SearchApproval extends Controller
{
private $request;
const stage_1 = Lang::get('message.failed');

trans it's a global function, so you can use it directly from your controller
trans 它是一个全局函数，因此您可以直接从控制器中使用它
trans('messages.failed');
but this won't work as constant, so you can use it like this:
但这不会像常数一样工作，因此您可以像这样使用它：
class SearchApproval extends Controller
{
private $request;
const stage_1 = 'message.failed';
public function xxx(){
$whatever = trans(self::stage_1);
}
}
UPDATED:
更新：
You can use this __('Your Text') inside the controller.
您可以在控制器内使用这个 __('Your Text') 。

Use trans('message.failed')instead of Lang::get('message.failed')https://laravel.com/docs/5.5/helpers#method-trans
