Calling all coders. Moving around a counter ??

[Johnnytoxic]

In php I have a count that goes 0,1,2 then goes back to 0.

If the count was on 1 how would i make it go back two places so that it would end up on 2 ??

any ideas.

Can I be cheeky and ask for an example. Googles bringing up lots of things
