Php 访问尚未创建的变量

我在这里遇到了一些问题，V_shop_menu$order_uuid没有填充。现在我猜这是因为它还没有被创建，这将在下面进一步完成。我遇到的问题是这里有两个语句对表进行插入，但它们都相互依赖

我有一点鸡和蛋的情况，因为我需要$shop\u menu\u uuid从顶部区域完成底部插入。我被引导去相信，因为他们是在同一个公共职能，这将只是工作，但事实并非如此

我需要做些什么才能做到这一点

谢谢

现在我猜这是因为它还没有被创建，这已经完成了 再往下看

是的，你是对的

这很简单。 插入不带

$order\u uuid的
v\u shop\u菜单
数据。
在插入
v_orders
后，获取
$order\u uuid
并使用
$shop\u menu\u uuid
更新
v_shop\u菜单
，
我知道这在技术上是可行的，但希望php函数能够节省额外的编码。谢谢
