Single Action Controller: Invokable Controller

In Laravel, I can create a Controller with only one method __invoke() by using

php artisan make:controller SearchController -i

Or I can manually add the public function __invoke to the Controller.

class SearchController extends Controller
{
    public function __invoke()
    {
        return ('This is for Search function');
    }
}

Then in the route file web.php, I can call the Controller directly, don't need to declare the method.

Route::get('/search', [SearchController::class]);

Noted here in case I forget and can quickly refer back later.
