Any ready-made classes for building complex trees (a tree-like grouping of objects into different categories)?

Task: there are objects, objects have sets of characteristics. Let's say the characteristics are an address and a color. It is necessary to build a tree, where at the first level - the address, at the second - the color, at the third - the objects of these addresses and colors. Or vice versa - first the color, then the address. And there are more than two characteristics. The language is PHP. Thank you.

I didn’t find any ready-made classes, but it was a long time ago and I didn’t really look for it :)
When I faced such a task, I just collected everything in associative arrays:

If we are talking about organizing and storing hierarchical data in a database, then I advise you to read the article " Hierarchical data structures and Doctrine " on Habré.
