i need to destroy only one session not all the sessions that workin at the same time
if i wrote


session_unset();
session_destroy();

that will destroy all the workin sessions i need to destrol only one session called $session[‘bids’]

If you just want to unset the one variable and not the whole session then just unset the variable rather than the session.

unset($session[‘bids’])
