I want to pass several parameters, but Yandex Money only Label can be used for its values.

$tariff_1 = '{"user_id":"'.$current_user['user_id'].'","tariff":"10","publications":"90"}';
$this->data['label_tariff_1'] = urlencode($tariff_1);

Eventually:
only 11 characters
and then

$label_arr = explode(";", $label);
echo $label_arr[0]; // uid - 99999
echo $label_arr[1]; // tariff - 10
echo $label_arr[1]; // publications - 90
