Answer 1

The DB façade is in the global namespace, so you need to import it at the top of your controller:
<?php namespace App\Http\Controllers;
use DB;
Have a read up on namespaces in PHP: http://php.net/manual/en/language.namespaces.php

Answer 2

Try this solution:
From Matt Burrow comment
Add a \ before DB like so; \DB or add use \DB; at the top.
So it should be like :
class LearnController extends Controller {
public function home()
{
$users = \DB::table('ads_new')->get();
foreach ($users as $user)
{
var_dump($user->title);
}
}
}
