session_unregister — Unregister a global variable from the current session
Description
session_unregister
( string
$name
) : bool
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 5.4.0.
Parameters
-
name -
The variable name.
Return Values
Returns TRUE on success or FALSE on failure.
Notes
Note:
If $_SESSION 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().

To unregister some session you can use:
<?php
// delete session
$_SESSION['NAME'] = array();
// start session
session_start();
// put info in session
$_SESSION['NAME']['userid'] = 5;
$_SESSION['NAME']['name'] "John Doe";
?>

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