关于PHP权限问题
目的描述：
系统中包含各个模块，模块下面又分为许多子模块，理论上是无限分级的模块。要实现对各个模块的各种权限操作。
现在有的权限包裹增、删、改、查，下载，发帖，上传权限，权限对应权限表，允许添加新权限。权限表数据结构（权限ID，权限名称，备注）。
每个模块包含权限表中的一种或多种权限，父级模块的权限子集模块不具有继承性，也就是说，对一个子集模块的父级模块具有修改权限，但是子集模块不会继承该权限。
用户的权限继承于用户组，通过调整用户组的权限来控制用户的权限。一个用户只能属于一个用户组，一个用户组可以拥有多个用户。
求解 怎么实现这样情况下的权限分配问题
------解决方案--------------------
没什么啊,对用户组授权,然后判断用户的用户组进行全选赋予.
鉴于你的权限不继承,只要判断当前模块id的权限就可以了,很简单的
------解决方案--------------------
可以参考Thinkphp 的做法！rbac,很方便的管理后台权限！
------解决方案--------------------
你不是说用户权限就是所在组的权限吗？用户的权限继承于用户组，通过调整用户组的权限来控制用户的权限。
既然你已经将所有组权限都保存到了缓存文件中了，那么还要查数据库干什么呢？
用户登录时，将所隶属的组保存于 session
进入模块时，加载相应组的权限缓存文件。你是以代码形式保存的，只需 include 即可
检查对该模块的权限，作出相应动作。就可以了呀

How to turn off private browsing authentication for iPhone in Safari?
Nov 29, 2023 pm 11:21 PM
In iOS 17, Apple introduced several new privacy and security features to its mobile operating system, one of which is the ability to require two-step authentication for private browsing tabs in Safari. Here's how it works and how to turn it off. On an iPhone or iPad running iOS 17 or iPadOS 17, Apple's browser now requires Face ID/Touch ID authentication or a passcode if you have any Private Browsing tab open in Safari and then exit the session or app to access them again. In other words, if someone gets their hands on your iPhone or iPad while it's unlocked, they still won't be able to view your privacy without knowing your passcode
