首先一个分页类,如下(摘自网络)可拷贝直接使用

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
