Menu tab show/hide upon login

Hi i’m looking to hide a page menu tab when a user is not logged in to my site. When they login the menu tab is revealed.

Someone had the same problem in another thread with a solution at the bottom of the thread:

I have limited understanding of php, but this seems like it would work?

Can anyone tell me if this is a good way to do this? Would anyone be able tell me what the code would be to show/hide a menu tab?
