Task:
- To create a function similar to scandir()
- As much information on each file and folder should be found as you can work out how to do
- The winner will be the person who finds the most things.

Rules:
- You can use any PHP function, but no external programs.
- No cheating.

Prize:
- Any game / codecanyon item under £10, see previous announcement for more info.
