Creating Tree Structure from associative array

Hi all, I have an associative array, which contains parent and child relationships. I've searched the web for creating a tree structure from this and found a few good sites but doesnt help 100% perhaps someone can point me in the correct direction? I've started to code it got to a point where I cant go any further, the code is pseudo code and dont want to reinvent the wheel. any suggestions would be really appreciated.
