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 end. However, CI seems to have its own session mechanism, which it claims is "better"

CI's session mechanism seems to store all the data in a cookie? Personally I like the idea of all the data being stored on the server, accessed with a cookie-key like PHPs native session mechanism... Am I being dumb thinking that's better? Should I just accept CI's mechanism? Or should I go ahead and use native PHP sessions?

What do you guys do?

Thanks,
Mala

In my experience with CI I've encountered some anomalies with its sessions, but for most day-to-day needs the library is good and easy to work with. As it was pointed out, Flashdata is a very nice feature.

If you choose to stay with CI's sessions, I'd strongly suggest to store sessions in a database and, additionally, encrypt cookies:

$config['sess_encrypt_cookie'] = TRUE; $config['sess_use_database']   = TRUE; $config['sess_table_name']     = 'sessions'; 

The database structure should be as follows:

CREATE TABLE IF NOT EXISTS  `sessions` (     session_id varchar(40) DEFAULT '0' NOT NULL,     ip_address varchar(16) DEFAULT '0' NOT NULL,     user_agent varchar(50) NOT NULL,     last_activity int(10) unsigned DEFAULT 0 NOT NULL,     user_data text NOT NULL,     PRIMARY KEY (session_id) );
