declaring your own session instead of session maintained by codeigniter

Is there any way to define your own session instead of session mainta开发者_如何学运维ined by codeigniter ?

$_SESSION['my_session_variable'] = 'this is my session variable content';

You'd use session this way if you want to.

You could use a native session variable as Thorpe showed, but using the native session library gives you a nice codeigniter-esque interface to work with sessions including flash data and so on.
