Unregistering a session using $_SESSION

Arc

is there a way to unregister a seesion using the $_SESSION or is the session_unregister() the way to go still?

Thanks!

have you tried unset($_SESSION['value'])?
Easiest way to find something like this out is to try it.

why not just give it a blank value?

<?php
$SESSION['foo'] = "barr";
//unregister
$SESSION['foo'] = "";
?>

or is that just silly?

Not hugely silly. But instead of setting it to "" it's better to set it to null - empty strings are still saved as session data, but nulls aren't. There was a bug in early 4.1.x that meant unset($_SESSION['foo']) didn't work - and setting them to null was the workaround, but that was fixed long ago and any reasonably current version doesn't have a problem with unset.

I was trying to use it for a "Log Out" code, but it didnt seem to work. If I used session_unregister("SESSION_NAME"); I would still be able to use the pages that were password protected. So I ended up using session_destroy(); and it works great.
