php分页功能怎么做？详解php封装实现实例-群英

上一篇：使用PHP怎样写一个多进程服务器？下一篇：php用gearman怎样做任务分发的操作？

我们在做开发的时候，如果数据太多就会使用分页功能。下面小编就给大家分享一个使用php封装实现的page分页类，感兴趣的朋友可以了解一下，下面是实现效果。

效果图

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;

?>
