PHP libraries for handling nested sets in MySQL

Question

I read this article. http://dev.mysql.com/tech-resources/articles/hierarchical-data.html

At the end of this article, it writes about PHP libraries for handling nested sets in MySQL.

Does anyone know which PHP libraries he is talking about?
