why hmget use array_values

[ajinisi]

This is source code:

    public function hmget($key, ...$dictionary)
    {
        if (count($dictionary) === 1) {
            $dictionary = $dictionary[0];
        }

        return array_values($this->command('hmget', [$key, $dictionary]));
    }

I don't understand why hmget use array_values. It makes me unable to get the mapping between name and value. I have to substitute 'command' for 'hmget' like

        Redis::hSet('h', 'field1', 'value1');
        Redis::hSet('h', 'field2', 'value2');
        dd(Redis::command('hmget',['h', ['field1', 'field2']]));
