unsetting session array

[sKunKbad]

//I have a session array :
$_SESSION['OfferListingId'][0]='bob';
$_SESSION['OfferListingId'][2]='ted';
$_SESSION['OfferListingId'][3]='mary';
$_SESSION['OfferListingId'][4]='jill';
$_SESSION['OfferListingId'][5]='spike';

//and when I try to unset the entire array using:
unset($_SESSION['OfferListingId']);

//it doesn't work. Why not?

session_unregister('OfferListingId');

 

or

 

$_SESSION['OfferListingId'] = array();

session_unregister('OfferListingId');

neither of those worked, but actually, i dont want to unset them, i want to completely delete them, so I was thinking something like this would work:

array_splice($_SESSION['OfferListingId'],0);

but it doesn't. I don't know what the heck is going on!
