PHP 分页实现类库

在PHP中实现分页功能可以通过自定义类库或使用现有第三方库完成。以下是几种常见实现方式：

自定义分页类实现

基础分页类示例代码：

class Pagination {
    private $totalItems;
    private $itemsPerPage;
    private $currentPage;
    private $totalPages;
    private $maxPagesToShow = 5;

    public function __construct($totalItems, $itemsPerPage, $currentPage) {
        $this->totalItems = $totalItems;
        $this->itemsPerPage = $itemsPerPage;
        $this->currentPage = $currentPage;
        $this->totalPages = ceil($totalItems / $itemsPerPage);
    }

    public function getHtml() {
        $html = '<div class="pagination">';
        if ($this->totalPages > 1) {
            // 上一页
            if ($this->currentPage > 1) {
                $html .= '<a href="?page='.($this->currentPage-1).'">«</a>';
            }

            // 页码
            $start = max(1, $this->currentPage - floor($this->maxPagesToShow/2));
            $end = min($this->totalPages, $start + $this->maxPagesToShow - 1);

            for ($i = $start; $i <= $end; $i++) {
                $active = ($i == $this->currentPage) ? 'active' : '';
                $html .= '<a class="'.$active.'" href="?page='.$i.'">'.$i.'</a>';
            }

            // 下一页
            if ($this->currentPage < $this->totalPages) {
                $html .= '<a href="?page='.($this->currentPage+1).'">»</a>';
            }
        }
        $html .= '</div>';
        return $html;
    }
}

使用方式：

$totalItems = 100; // 总记录数
$itemsPerPage = 10; // 每页显示数
$currentPage = isset($_GET['page']) ? $_GET['page'] : 1;

$pagination = new Pagination($totalItems, $itemsPerPage, $currentPage);
echo $pagination->getHtml();

使用第三方库

Pagerfanta 安装：

php分页实现类库实现

composer require pagerfanta/pagerfanta

基本用法：

use Pagerfanta\Pagerfanta;
use Pagerfanta\Adapter\ArrayAdapter;

$adapter = new ArrayAdapter($yourDataArray);
$pagerfanta = new Pagerfanta($adapter);
$pagerfanta->setMaxPerPage(10);
$pagerfanta->setCurrentPage($_GET['page'] ?? 1);

// 获取当前页数据
$currentPageResults = $pagerfanta->getCurrentPageResults();

// 渲染分页
echo $pagerfanta->getCurrentPage();

Laravel Pagination Laravel内置分页功能：

php分页实现类库实现

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

在视图中显示：

{{ $users->links() }}

数据库分页查询

MySQL分页查询示例：

$page = isset($_GET['page']) ? (int)$_GET['page'] : 1;
$perPage = 10;
$offset = ($page - 1) * $perPage;

$sql = "SELECT * FROM articles LIMIT $offset, $perPage";
$result = $conn->query($sql);

前端配合

Bootstrap分页样式示例：

<nav aria-label="Page navigation">
  <ul class="pagination">
    <li class="page-item"><a class="page-link" href="#">Previous</a></li>
    <li class="page-item active"><a class="page-link" href="#">1</a></li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item"><a class="page-link" href="#">Next</a></li>
  </ul>
</nav>
