Best practices in session variable names

Question

I'm used to calling my session variables in the “normal” way, sort of like when I want to track user details, I call them:

• $_SESSION['username']
• $_SESSION['email']
• $_SESSION['id']

I am worried that they may conflict with other session data when I browse sites in one browser or there will be no conflicts at all (once I tried to run two of my projects with the same session, variables living on the same server, and obviously everything became useless).
