use Illuminate\Support\Facades\DB;
use App\Http\Controllers\Controller;

class UserController extends Controller
{
    /***

    *@param int $id
    *@return Response
    *@author ebookApp
    **/
    public function show($id,$name)
    {
        $users = DB::select('select id,title,video,created from laravel_users'); //依赖 extension=php_pdo_mysql.dll
        
        dump($users);
        //return "Hello,".$id.$name;
        //return     view('user.profile',['user'=>User::findOrFail($id)]);    
        return view('helloworld',['id'=>$id,'name'=>$name,'records'=>30]);
    }
    
    public function list($id)
    {
        return "123456789-".$id;
