Could you elaborate on what you're lost on and what you'd like me to rephrase?

I can't fresh my mind.  The var1 to var3 have different and also empty().  It is same thing for isset(). 

 

Actually, I thought that there is only one var that something to clear out for one example but it has three examples (i.e. var1, var2, var3).

I am not sure why do I have to know about them.

So the examples are just trying to demonstrate what it means to be "set", "empty", and "numeric" and uses a couple of different values--represented by variables--to do so.
