This competition is now over.

All of the entries that got the right idea are posted below.

the winning entry was submitted by Tino (the moderator) and is shown below.

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.
