implementation of tree data structure in php
I'm new to PHP world and I'm looking for tree data structure implementation in PHP. It should be effective in terms of speed / memory usage. In ideal world it would be great to compare various implementations and choose one that runs better on my specific test workloads.  Any analogues of Java / C# generic collections classes? Any hints, suggestions?
