Is it possible to count the number of dimensions in an array?

[aragorn]

I want to be able to know the level of an array as it is being built.The code loops through a bunch of directories to create a massive multi-dimensional array.As the array is being created, I want to know how deep in the array I am.\[code\]1 2 3 4---------------------Root A A2 A3 A4 A4a B B2 B3 C D E E2 E2a E3\[/code\]In the example above, the root directory is in level 1. All single uppercase letters are in level 2. All uppercase letters with a number are in level 3. All uppercase letters with a number and a lowercase letter are in level 4.As I'm building the array, is there any way for me to know which level I'm in? The array is being created with a recursive function.This is a PHP question.
