Load Dynamic Model

Add the "use" statement above your class.

I.e.

use App\Models\RolesModel;

class x extends Controller {

}

This is top of my Controller :

Code:

namespace App\Controllers;

use CodeIgniter\Controller;
use App\Models\UsersModel;
use App\Models\RolesModel;
use App\Models\PermissionsModel;


class BaseController extends Controller
{

so when i use this syntax 

Code:

$UsersModel = new RolesModel();

work fine  without any problems !!!
wheen 

Code:

$variable = "NameOfModel";
$UsersModel = new $variable();

not work 

any idea !!
