[RESOLVED] Cleaning sessions

[bipster]

Is there an easy way of cleaning a whole session except some of its variables? This is my session:

$SESSION['a']=
$SESSION['b']=
$SESSION['c']=
$SESSION['d']=
$SESSION['e']=
...
$SESSION['z']=

For example, I want to unset everything except $_SESSION['c']. Do I have to scan and unset the individual variables one by one?

[NogDog]

$temp = $_SESSION['c'];
$_SESSION = array('c' => $temp);

Thank you very much! 🙂

You could also do it on one line:

$_SESSION = array('c' => $_SESSION['c']);

Either way, don't forget to mark this thread resolved.
