这篇文章主要介绍了PHP封装的page分页类定义与用法,结合完整实例形式分析了php封装的page分页类具体定义、数据库连接、查询、样式及调用等相关操作技巧,需要的朋友可以参考下

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

<?php
header("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;
?>
