Fetching (and displaying) the 3 newest items from MySQL

Hi, I'm a newbie in need of your great wisdom. I need help on how to fetch the three most newly added items from a specific table in a MySQL database. The records in the table are NOT dated, but they do contain have an ID, that is highest for the most newly added item. So, what I want to do is: 1. Take the table and order it with the highest ID first 2. And then take the first 3 items. 3. After that, I also need to display the 3 items, of course! Can you please help me? I'm very new to PHP, but so far I'm very impressed by it! /Mattias
