Laravel手动分页的方法

use Illuminate\Pagination\LengthAwarePaginator;

public function index(Request $request){
    $list =[...];
    //当前页数 默认1
    $page = $request->page ?: ;
    //每页的条数
    $perPage = ;
    //计算每页分页的初始位置
     $offset = ($page * $perPage) - $perPage;
     //实例化LengthAwarePaginator类，并传入对应的参数
     $list = new LengthAwarePaginator(array_slice($list, $offset,
     $perPage, true), count($list), $perPage,$page, ['path' =>
     '', 'query' => $request->query()]);
     return view('admin.user.index', compact('list'),
     compact('query'));
}
