如何在laravel中获取列表的第一个元素？

My problem is not difficult :) i use Laravel 4, and i just want to get the first element of my list, my code is :

public function index()
{
    $userid = User::lists('id'); // here i want to get the first element of my list
    $services = User::find($userid)->service;
    $username = User::lists('username');

    return View::make('services.index',array('services'=> $services,'username'=>$username));
}

so if someone has any idea i will be very appreciative :)

Within Laravel, the 'lists' method returns an array. So, you may simply access the first object in the array by using something like:

$userid[0] = $firstUserId;

If you don't need the list but just the first item:

$user = User::first();

$userid = $user->id
$services = $user->service;
$username = $user->username;
