Within Laravel, the 'lists' method returns an array. So, you may simply access the first object in the array by using something like:
在 Laravel 中，'lists' 方法返回一个数组。因此，您可以简单地使用以下内容访问数组中的第一个对象：
$userid[0] = $firstUserId;

If you don't need the list but just the first item:
如果您不需要列表而只需要第一项：
$user = User::first();
$userid = $user->id
$services = $user->service;
$username = $user->username;
