namespace App\Http\Controllers;

use Illuminate\Database\Eloquent\Collection;
use Illuminate\Http\Request;

class TestController extends Controller
{
    
    public function index()
    {
        $col= new Collection([
            ['Data0'],
            ['Data1'],
            null,
            [],
            ]);

use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\TestController;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
 
Route::get('/', [TestController::class,'index']);

php artisan serve

Then launch your browser with URL http://localhost:8000/ to see the collection result. 

Illuminate\Database\Eloquent\Collection {#1863 ▼
  #items: array:2 [▼
    0 => array:1 [▼
      0 => "Data0"
    ]
    1 => array:1 [▼
      0 => "Data1"
    ]
  ]
}
