session_unset
Description
void session_unset ( void )The session_unset() function frees all session variables currently registered.
Note: If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset() to unregister session variable. i.e. $_SESSION = array();
| Caution |
Do NOT unset the whole $_SESSION with unset($_SESSION) as this will disable the registering of session variables through the $_SESSION superglobal. |
