How can I use php file as an array, instead of class in Laravel 5?

This is my file with array for seeding DataBase:

<?php

namespace App\MyFolder;

return [
  [
    'name' => 'manufacturing firm',
    'values' => [
        'test1',
        'test 2',
        'test 3',
    ],
  ],
];

Then I try to use it inside my controller:

<?php

namespace App\Http\Controllers;

use App\MyFolder;

class UserController extends Controller
{
   public function index() {

     //.... error class not found  
     return MyFolder;
   }

}

How can I use arrays, but non-class based files?
