You can do whatever you want, of course.

Sessions just make your code easier and portable and more people will be
able to understand what you're talking about.

Sessions are just a way to pass a variable between pages. You assign a
variable to the session, and you retrieve it on any other page that has a
session. that's it. You can use regular variables or arrays...
