[PHP] Returning reference problem
Starting over since my last thread had too little effort put in it. I
have this script that should create a multi-demensional array that would
resemble a directory structure. The problem is that after adding one
element to a folder it appears to be creating a new object instead of
adding another item to the current object. So there can only be one
file or folder in the parent folder with the exception of the top
level. My entire script is below.
Thanks, Jon
