Laravel手动分页实现方法详解

#vendor/laravel/framework/src/Illuminate/Database/Eloquent/Builder.php:480
public function paginate($perPage = null, $columns = ['*'], $pageName = 'page', $page = null)
{
    $query = $this->toBase();
    $total = $query->getCountForPagination();
    $this->forPage(
      $page = $page "htmlcode">

public function __construct($items, $total, $perPage, $currentPage = null, array $options = [])
{
    foreach ($options as $key => $value) {
      $this->{$key} = $value;
    }
    $this->total = $total;
    $this->perPage = $perPage;
    $this->lastPage = (int) ceil($total / $perPage);
    $this->path = $this->path != '/' "htmlcode">

[
  ['username'=>'zhangsan', 'age'=>26],
  ['username'=>'lisi', 'age'=>23],
  ['username'=>'wangwu', 'age'=>62],
  ['username'=>'zhaoliu', 'age'=>46],
  ['username'=>'wangmazi', 'age'=>25],
  ['username'=>'lanzi', 'age'=>24],
  ['username'=>'pangzi', 'age'=>21],
]




共7条数据，每页显示3条，共3页


use Illuminate\Pagination\LengthAwarePaginator;
use Illuminate\Pagination\Paginator;
use Illuminate\Http\Request;
# 仅做演示 #
function userList(Request $request) {
  $users = [
    ['username'=>'zhangsan', 'age'=>26],
    ['username'=>'lisi', 'age'=>23],
    ['username'=>'wangwu', 'age'=>62],
    ['username'=>'zhaoliu', 'age'=>46],
    ['username'=>'wangmazi', 'age'=>25],
    ['username'=>'lanzi', 'age'=>24],
    ['username'=>'pangzi', 'age'=>21]
  ];
  $perPage = 3;
  if ($request->has('page')) {
      $current_page = $request->input('page');
      $current_page = $current_page <= 0 "color: #0000ff">$paginator ->setPath('路径') 设置。

页面中的分页连接也是同样的调用方式：


{{ $paginator->render() }}



好了，基本就是这样，有纰漏的地方欢迎指正！
