Пришлось подправить, то что выше не работало:

function rpcf_get_sup() { //0x8011
                $ret=array();
                if (!$this->connection->urfa_call(0x8011)) {
                        print "Error calling function ". __FUNCTION__ ."\n";
                        return FALSE;
                }
		$x = $this->connection->urfa_get_data();// Tariff count
                $count = $x->DataGetInt();
                $ret['count'] = $count;
                for ($i=0;$i<$count;$i++) {
                    $x = $this->connection->urfa_get_data();
 
                    $sup['id']=$x->DataGetInt();
                    $sup['name']=$x->DataGetString();
                    $sup['ur_adress']=$x->DataGetString();
                    $sup['act_adress']=$x->DataGetString();

                    $sup['bank_kschet']=$x->DataGetString();
                    $ret[]=$sup;
 
                }
    $this->connection->urfa_get_data();
                return $ret;
   }
