IF statements in PHP - a little help, it's easy if you know how!?

[whhhhaaaazzzzuuuuuppppppp]

I have a user login using databases and PHP.

There are 3 tiers of users, each tier has different options after they login. Some have few links, and some many more.

My IF statement works well for this.

If user = tier 1 then give these links.
else
give these links.


because IF statements say if this isnt the case do that... how can i work with 3 tiers IF statements?

IF 1

Do this

IF 2

Do that

Else

Do the other
