session_unset
(PHP 4, PHP 5)
session_unset — Free all session variables
Description
void session_unset
( void
)
The session_unset() function frees all session variables currently registered.
Return Values
No value is returned.
Notes
Note: If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset() to unregister a session variable, i.e. unset ($_SESSION['varname']);.
Caution
Do NOT unset the whole $_SESSION with unset($_SESSION) as this will disable the registering of session variables through the $_SESSION superglobal.
