Displaying latest files in a folder (?)

[Angry_Coder]

Hello,

I have:

1.txt, 2.txt, 3.txt, 4.txt and 5.txt. Soon I will and 6.txt, 7.txt, etc...
I have these files in a folder named "data", how I can display the content of the last 3 files dynamically?!

In MySQL I use the LIMIT clause with "DESC", but I am using flat file this time :p

Thank you.
