remusHello,
I'm interested in PHP developing and nowadays I'm studying all sorts of methods of handling hierarchical data in or out a MySQL database. I found a few methods but I would like to know which one is the best. Now, since I'm a huge Drupal and WordPress fan and they for certain use one of this methods in their code to handle their infinite hierarchical complex navigational structures and because I'm not that good yet to understand that by myself, I am wondering: what database handling method did they use to output their tree like navigations systems?
Thank you!
