PHP/Mysql Re-order script

What i need is help in creating a "re-ordering" script.Something along what PHPBB's (i think Vbull uses it too... im not sure) forum uses.

Where i can reorder tables/categories with a click of a button.

If ANYONE has an example or things that will help me.

Plz post them.

Thanks.
