Question

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.

1    2    3    4
---------------------
Root
     A
          A2
          A3
          A4
               A4a
     B
          B2
          B3
     C
     D
     E
          E2
               E2a
          E3

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.

One quick an easy answer is to simply add a “depth” parameter to your function and increment it when the function calls itself.
