New to Code Igniter & $_SESSION?

@Richie Jenkins,

There are several reasons for not using PHP's native sessions:
- they are not secure (the session id is a simple non-encrypted cookie without any checks)
- they are file based, and depending on the host config not always very secure (you can access other website's session files if not configured carefully)
- they are file based, so you can't query them (for example to get the number of logged-in users)
- they don't scale as well as a database does (not much of an issue in a single-server setup)
and probably lots more.

For me, the security issues alone are reason enough not to use them.
