thinkphp实现分页

public function zhanshi(){
$cate = M(\'cate\');       //实例化数据表
        $count      = $cate->count();     //获取总的记录数
        $Page       = new \Think\Page($count,2);      //实例化分页类
        $show       = $Page->show();                 //组装分页字符串
        $starno     = $Page->firstRow;               //起始行
        $pagesize   = $Page->listRows;               //页面大小
        $res=$cate->limit("$starno,$pagesize")->select();   //获取每页的数据
        $this->assign(\'res\',$res);            // 数据赋值
        $this->assign(\'show\',$show);          //分页类赋值
        $this->display();
