Why doesn't this simple Lavarel class example work?

Question

Laravel

Hello! For some reason I can't create the class

<?php
namespace App\Http\Controllers;
use DB;
use App\Http\Controllers\Controller;
class Test extends Controller {}
?>

When running the file:
/usr/bin/php /home/******/*****/****/*****/app/testclass.php
PHP Fatal error: Class 'App\ Http\Controllers\Controller' not found in /home/*******/******/****/*****/app/testclass.php on line 5

Answer 1

Class 'App\Http\Controllers\Controller' not found

Right, well, what can be unclear here?
