CodeIgniter sessions vs PHP sessions

Question

I\'m relatively new to CodeIgniter and am making my first CI project in which there are user-accounts, etc. In the past, I have always used PHP\'s $_SESSION variable to this

Answer 1

The manual says more flexibility rather than better ;-)

I presume the main benefit of CodeIgnite session class is that it integrates with the framework and it offers a few extra functionality, such as IP address tracking and what it calls flashdata (session data that's erased as soon as it's read). If you are using a framework in the first place that means these options may be attractive for you.

Whatever, you can also save session data into a database:
