laravel手动创建数组分页的实现代码

//控制器中
$users = DB::table('users')->paginate(15);
return view('user.index', ['users' => $users]);

//视图中
{{ $users->links() }}

//控制器中
$users = User::where('votes', '>', 100)->simplePaginate(15);
return view('user.index', compact('users'));

//视图中
{{ $users->links() }}

public function __construct($items, $total, $perPage, $currentPage = null, array $options = [])
 {
  foreach ($options as $key => $value) {
   $this->{$key} = $value;
  }

  $this->total = $total;
  $this->perPage = $perPage;
  $this->lastPage = max((int) ceil($total / $perPage), 1);
  $this->path = $this->path !== '/' ? rtrim($this->path, '/') : $this->path;
  $this->currentPage = $this->setCurrentPage($currentPage, $this->pageName);
  $this->items = $items instanceof Collection ? $items : Collection::make($items);
 }

//控制器中
public function index(LiveService $liveService, Request $request)
 {
  //数据A
  $dataA = User::where('status', 1)->get()->toArray();
  //数据B
  $dataB = User::where('status', 2)->get()->toArray();
  $data = array_merge($dataA, $dataB);
  //当前页数 默认1
  $page = $request->page ?: 1;
  //每页的条数
  $perPage = 4;
  //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
  $data = new LengthAwarePaginator(array_slice($data, $offset, $perPage, true), count($data), $perPage,
   $page, ['path' => $request->url(), 'query' => $request->query()]);
  return view('admin.users.index', compact('data'));
 }

//视图中
{{ $data->links() }}
