tp框架之分页与第三方类的应用

public function xianshi()
    {
        $c = D("chinastates");
        
        $shuliang = $c->count();  //查询总条数
        $page = new \Home\libs\Page($shuliang,15);  //实例化分页类并传参数
        
        $xinxi = $page->fpage();  //按照参数获取共几页等信息
        
        $attr = $c->limit($page->limit)->select();  //根据分页信息查询
        $this->assign("shuju",$attr);
        $this->assign("xinxi",$xinxi);
        $this->show();
    }
