TP5分页返回数据处理;分页转数组

第一次摸tp5的时候分页做的的确挺头疼，用 paginate 得到的数据直接用foreach会报错，后来选择了php转数组方法放到common里面用了好久，偶然看手册发现还有一个 toArray 属性，瞬间想给不认真看手册的自己一拳。

demo:

public function demo(){
    $member_id = Session::get("member_id");
    $where['member_id'] = $member_id;
    $quan_list = Db::name('member_quan')->where($where)->order("create_time desc")->paginate(10);
    $page = $quan_list->render();
    $quan_to_array = $quan_list->toArray();
    $quan_list_array = $quan_to_array['data'];
    if(isset($quan_list_array) && !empty($quan_list_array)){
        foreach($quan_list_array as $key=>$item){
            //转换成的二维数组可以直接追加元素，用以前台输出
            $coupon_id = $item['coupon_id'];
            $coupon_info = Db::name("quan_list")->where("id",$coupon_id)->find();
            $quan_list_array[$key]['quan_name'] = $coupon_info['quan_name'];
            $quan_list_array[$key]['quan_price'] = $coupon_info['quan_price'];
            $quan_list_array[$key]['end_time'] = $coupon_info['end_time'];
            $quan_list_array[$key]['quan_code'] = $coupon_info['quan_code'];
        }
    }

    $this->assign("quan_list_array",$quan_list_array);
    $this->assign("page",$page);
    return $this->fetch('member_coupon');
}
