Here is my code
$user1 = new stdClass();
$user1->id = 16;
$user1->city = 'some city';
$params = array('users'=>array($user1));
$functionname = 'core_user_update_users';
/// SOAP CALL
$serverurl = $domainname . '/webservice/soap/server.php' . '?wsdl=1&wstoken=01f08c3c85b69758f03d6xxxx';
$client = new SoapClient($serverurl);
$resp = $client->__soapCall($functionname, array($params));
