session_start
If globals is on, you'll have to unset the $_SESSION[varname] as well as the $varname.
Like:

unset($varname);
session_unregister
(PHP 4, PHP 5)
session_unregister — Unregister a global variable from the current session
Description
bool session_unregister
( string $name
)
session_unregister() unregisters the global variable named name from the current session.
Warning
This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 6.0.0. Relying on this feature is highly discouraged.
Parameters
- name
-
The variable name.
Return Values
Returns TRUE on success or FALSE on failure.
Notes
Note: If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset() to unregister a session variable. Do not unset() $_SESSION itself as this will disable the special function of the $_SESSION superglobal.
Caution
This function does not unset the corresponding global variable for name , it only prevents the variable from being saved as part of the session. You must call unset() to remove the corresponding global variable.
Caution
If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered() and session_unregister().

as a side note you must have session_start() set inorder to actually unregister the session varibles.
