How to destroy specified session

Question

Assume that I have this session

$_SESSION['LAST_ACTIVITY_For_Admin']

How to destroy that specific session, and not all sessions that session_destroy() does?

thanks

Answer 1

Assuming you meant "variable" - exactly the same way you would "destroy" any other variable:

unset($_SESSION['LAST_ACTIVITY_For_Admin']);

Answer 2

$_SESSION['LAST_ACTIVITY_For_Admin']= '';

or

$_SESSION['LAST_ACTIVITY_For_Admin']= NULL;

or

unset($_SESSION['LAST_ACTIVITY_For_Admin']);
