Actually I am running a site where new members can join with the reference of a existing member this is how a tree structure of members are formed.
So, I want a PHP program for my website to mangage and display names of my site members in a hierarchical tree structure.
So, I was looking for any complete php software (like phpbb ,SMF etc) where I can manage such structure of names in a web-based manager. And with a search option to search names and display that name with complete tree path for that member name.
Best would be a graphical hierarchical chart to disply members and their sub-members with the search option, of not at least like a windows directory structure with search option.

If you know any such PHP package to sute my purpose please tell. Or any other type of package (may not be for that job) which can be used to solve that specific purpose.
I would manually enter the whole members data, so i don't need a specific platform which will need my exixting data structure to fit. It can have it's own database.
