You can do so much more with storing sessions in a database. For example, I can determine which of my users is currently on by looking in the sessions table. Not only does using a database for sessions offer more security, it also offers more flexibility.

Take care,

As Floyd suggested keeping your sessions in the DB will give you better
session management and security as well.

Why would putting the session data in a database offer more security? I'm not meaning to try and poke holes in your idea, I genuinely don't
know the answer!

*Storing Session Data In A Database
*When you use on-disk files to store session data, those files must be
readable and writeable by PHP. On a multi-user hosting system, it is
possible for other users to access your session data through the PHP process (but see the commentary on open_basedir in part 5 of this series. The best
way to secure your session data is to store it in a database.


I have also studied Zend Certification Study guide by Davey Shafik and Ben
Ramsey who said similar things in the book.


And is the database not readable and writeable by PHP? Just seems that
this sort of thing could be properly sorted by the right permissions
level on the file, as I assume you'd be protecting the database in a
similar manner by locking down that to specific users, and determining
what they could and couldn't do.
