[Cialug] phpmysql ?

[David Champion]

They're meant to be used as system key fields... and not to be user read 
/ written. They will get all out of sequence any time records are added 
/ deleted.

If you need a "natural key" field like "firstname + lastname" then 
that's a different story.

So, short answer is - don't worry about it.
