managing hierarchical data ??

[PHPycho]

Hello forums !!
I have some few questions regarding storing hierarchical datas in the table.
I would like to store hierarchical data in following table format
id | title | parent_id

I would like to know , whats the effective means of editing, adding , deleting the hierarchical datas, what i mean is how they should be displayed and operation should be performed.
Thanks in advance to all of you.

Search the forums. There's been a few instances where this has been discussed. Look up "recursion", "recursive arrays", "hierarchical data". I had a thread we ran through this on too.
