All you need to do is redifine what the $_SESSION['client'] array's
definition is:

$_SESSION['client'] = array('name' => $_SESSION['client']['name']);

Don't mix session_*register() functions with the use of $_SESSION.
Those functions are only there for old scripts to work, see
http://php.net/session_unregister (the second Caution)

To register a session var:

$_SESSION['client'] = $client;

To unregister a session var:

unset($_SESSION['client']);
