PHP 完美分页
首先一个分页类,如下(摘自网络)可拷贝直接使用
- <?php

- 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);?>
