用array_slice实现分页

<?phpheader("Content-type:text/html;charset=utf-8");$mysqli = new mysqli('127.0.0.1','root','0417','drill');$mysqli -> query("set names utf8");$sql = "select * from page";$res = $mysqli -> query($sql);while($rows = $res->fetch_assoc()){$data[] = $rows;}//当前页面$pages=1;$num = count($data);//设置每页显示的条数$number = 2;//设置总页数$pagesize = ceil($num/$number);//设置偏移量 $start = ($pages-1)*$number; //$data  总数组//$start  取出元素开始出//$number  取出多少条//ture  保留键名 $newpage = array_slice($data,$start,$number,true); // print_r($newpage);exit; ?>
