php
1.在think目录下新建文件Page.php
2.写如分页封装

use think\Page;
4.调用静态类传入地址和数据库
$data = Page::mypage(‘地址后面接上?page=‘,‘数据库‘);
5.取出数据
$result = $data[‘sql‘];
6.取出分页
$page = $data[‘page‘];
7.把数据传入前端页面展示出来
$this->assign(‘result‘,$result);$this->assign(‘page‘,$page);
html页面
<!DOCTYPE html><html lang="en"> ???<head> ???</head> ???<body> ???????{volist name="result" id="v"} ???????????数据 ???????{/volist} ???????{$page} ???</body></html> ???????????最后根据所给类名设置css样式
里面页码和显示数据条数都是可以自己设置
thinkphp分页封装
