关于PHP权限设计解决办法

关于PHP权限设计
描述：想做一个PHP的权限菜单、根据不同的用户登录从数据库中循环出不同的主菜单及子菜单
数据库结构如下
cfg_useraccount \\存储用户信息
cfg_role \\存储角色信息
cfg_resource \\存储菜单信息
cfg_permission \\角色拥有的权限

现在是可以通过登录时获取的用户ID、取到该用户所拥有的主菜单、但是如果取到该用户所拥有的子菜单呢、一般对于子菜单应该如何处理？暂时没有啥头绪
\\select a.RoleID,b.ResourceName,b.URL from cfg_permission a join cfg_resource b on a.ResourceID=b.ResourceID where RoleID in (select RoleID from cfg_useraccount where username='admin');

------解决方案--------------------
一些建议

1.表似乎可以合并成一个
2.关于权限，你可以在读取权限后赋值给session
然后根据权限include 菜单/子菜单内容

权限判断当然是要用到if 的，这是应该让php来做的，而不是让mysql来"读取"的.

将权限判断写成一个类，然后include不同的文件就好了
