Learing laravel and have problem with getURLList();

Im trying to learn Laravel framework and having trouble with getURLList();

In the tutorial that im following it says.

class StudInsertController extends Controller
{
    
    public function insert(){
        $urlData = getURLList();
        return view('stud_create');
    }

But the getURLLIST(); comes back as

Call to undefined function App\Http\Controllers\getURLList()

And i dont find any information about that. Is it because the tutorial is for older version of Laravel?

The link to the tutorial itself is here:

https://www.studentstutorial.com/laravel/insert-data-laravel

Can somebody point me in the right direction.
