首先一个分页类，如下（摘自网络）可拷贝直接使用
<?php
/*
* Created on 2013-12-3
* 分页类

*/
class Pagination {
private $each_disNums; //每页显示的条目数
private $nums; //总条目数
private $current_page; //当前被选中的页
private $sub_pages; //每次显示的页数
private $pageNums; //总页数
private $page_array = array (); //用来构造分页的数组
private $subPage_link; //每个分页的链接
private $subPage_type; //显示分页的类型
/*
__construct是SubPages的构造函数，用来在创建类的时候自动运行.
@$each_disNums 每页显示的条目数
@nums 总条目数
@current_num 当前被选中的页
@sub_pages 每次显示的页数
@subPage_link 每个分页的链接
@subPage_type 显示分页的类型
当@subPage_type=1的时候为普通分页模式
example： 共4523条记录,每页显示10条,当前第1/453页 [首页] [上页] [下页] [尾页]
当@subPage_type=2的时候为经典分页样式
example： 当前第1/453页 [首页] [上页] 1 2 3 4 5 6 7 8 9 10 [下页] [尾页]

在需要分页的php文件中
include_once ("Pagination.php");
//每页显示的条数
$pageSize = 10;
//总条目数
$pageTotal = $db->get_var("select count(*) from tb");
//每次显示的页数
$sub_pages = 10;
//得到当前是第几页
if (is_array($_GET) && count($_GET) > 0) {
if (isset ($_GET["p"])) { //是否存在"id"的参数
$pageCurrent = $_GET["p"];
}
} else {
$pageCurrent = 1;
}
$goodses = $db->get_results("SELECT g.id,* FROM tb as g INNER JOIN (select id from tb order by updatetime desc limit " . ($pageCurrent -1) * $pageSize . ",10 )as g1 ON g.id=g1.id");显示分页数据
<?php $subPages = new Pagination($pageSize, $pageTotal, $pageCurrent, $sub_pages, "index.php?p=", 2);?>
