Hierarchical RBAC implementation in PHP?

I had similar research on ACL but it ends with no light at end of tunnel :).

(that has hierarchy). First, if you don't, and if you don't have a framework of choice already, then I strongly recommend you go a step back, research, and choose such a framework. I see very little point in developing PHP based apps from scratch.

Even very small and target oriented apps could use some parts of a framework.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
