laravel自定义分页的实现案例offset()和limit()

  $pagenNum=request('page');
  $limit=request('limit');
  $count=Admin::count();
  $page=$pagenNum-1;
   if ($page != 0) {
    $page = $limit * $page;
    $limit=$limit*$pageNum;
   }
  $data = Admin::offset($page)->limit($limit)->get()->toArray();
  return response([
   'code'=>'0',
   'msg'=>'',
   'count'=>$count,
   'data'=>$data]);
