use think\Model;
collection()->toArray();
$result = collection(model("Menu")->order("listorder asc,id asc")->select())->toArray();


或是在模型里写
namespace app\admin\model;

class Menu extends \think\Model
{
protected $resultSetType = 'collection';
}

控制器
$result = model("Menu")->order("listorder asc,id asc")->select()->toArray();
