Celling class model and function model

So what problems are you having? That tell's nothing about your problem.

It would be something like this:

PHP Code:

// Loading a model in the Controller.
$users = new UserModel();

// Using the Model in the Controller.
$user = $users->getUserById($id); 


If that is what you are looking for.

do not forget to add the model at the beginning of the controller:

PHP Code:

use App\Models\UsersModel;
