      使用教程，代码如下：
      <?php $sql="select * from php_orders where 1=1 "; if(!empty($_REQUEST['ordersn'])){ $sql.=" and ordersn like '%".$_REQUEST['ordersn']."%' "; } if(!empty($_REQUEST['delivery'])){ $sql.=" and delivery = ".$_REQUEST['delivery']; } $sql.=" order by orderid desc"; //page start $db->query($sql); $page_total = $db->db_num_rows(); $page_perpage = 5; $page_current = $_GET['page'] ? intval($_GET['page']) : 1; //当前第几页 if (strpos($_SERVER['REQUEST_URI'],'page=')){ $page_url = preg_replace('/page=(\d+)/', 'page=#page#', $_SERVER['REQUEST_URI']); } elseif (strpos($_SERVER['REQUEST_URI'],'?')){ $page_url = $_SERVER['REQUEST_URI'] . '&page=#page#'; } else { $page_url = $_SERVER['REQUEST_URI'] . '?page=#page#'; } $page_html = page($page_total, $page_perpage, $page_current, $page_url, array('class' => 'pagenavi')); //page end $db->query($sql.' limit '.($page_current-1)*$page_perpage.','.$page_perpage); while($row = $db->fetch_array()){ echo $row['orderid']; } echo $page_html;
