PHP封装的page分页类定义与用法完整示例

时间：2021-05-26

本文实例讲述了PHP封装的page分页类定义与用法。分享给大家供大家参考，具体如下：

亲测有效，见下图=========>

1. 测试实例test.php

<?phpheader("Content-Type: text/html; charset=utf-8");date_default_timezone_set("Asia/Shanghai"); //时区require_once('page.class.php');$showrow = 5;$curpage = empty($_GET['page']) ? 1 : $_GET['page'];$url = "?page={page}";$dsn = 'mysql:host=xxx.xxx.80.xxx;dbname=admin';$pdo = new PDO($dsn, 'root', 'root');$pdo->query('set names utf8');$sql = "SELECT * from operator_list where 1=1";$res_gg = $pdo->query("SELECT count(*) as ctn from operator_list where 1=1;");$result = $res_gg->fetch();$total = $result["ctn"];if (!empty($_GET['page']) && $total != 0 && $curpage > ceil($total / $showrow)) { $curpage = ceil($total_rows / $showrow);}$sql .= " LIMIT " . ($curpage - 1) * $showrow . ",$showrow;";$res_zz = $pdo->query($sql);$result = $res_zz->fetchAll();//print_r(json_encode($result));die;?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://</a></div></body></html>

2. 封装的page分页类page.class.php
