Laravel: Class 'App\DB' not found

Question

I am trying to use DB class to run query. I have used it in my controller like this:

use \DB;

And I am using it in my code like this:

$changeCar = DB::select(DB::raw($query));

I have tried including it like this:

use Illuminate\Support\Facades\DB

But still the same. Also, tried it with the backslash in the code and not including it like this:

$changeCar = \DB::select(\DB::raw($query));

My Code:

namespace App\Http\Controllers;


use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use \DB;


class TicketsController extends Controller
{
    public function myTickets()
    {
        $user = Auth::user();
        $changeCar = DB::select(DB::raw($query));
    }
}

Still the same. What am I doing wrong here? Any help?

P.S: My laravel version is 5.4.33

DB is a facade in Laravel. So just doing Use DB; should work. Can you check if you have opcache enabled on your php.ini ?

Look up php.ini for opcache_enabled=1 and change the value to 0. Then restart your nginx/apache server and try again.
