Ok, sounds good. Any hints? I've not touched this stuff before.. Will using classes allow multiple objects to be running at the same time making the script faster?

The menu class will have variables of id, parent, title, children, and tree. The children will be initialised to 0 and tree will be initialised to 1. You will need to write a function to find any menu object given the menu's ID, should be easy if you store each object in an array (keyed on the ID) 1) Read in a record and create a menu object 2) Get the parent object, using the parent variable and the find method 3) Increment the children variable in the parent menu object by one 4) Set the tree variable in the new menu object to the tree object in the parent object plus the value in the children object. Now add method to display the menu items and your problem should be solved.
