Why is this code throwing the following errors? Thanks.

wel your main problem is that your calling DirTree() instead of DirTree(somthing).

your DirTree takes one arg but your giving it nothing so when it try to run it can't find a no-arg version of DirTree so it complains.

on line 58 is where your error starts
[PHP]$class = new DirTree();[/PHP]
