function updatezsetscorewithlua($key, $member, $increment) {
    global $redis;
    $luascript = "
    local member = argv[1]
    local increment = tonumber(argv[2])
    local zsetname = keys[1]
    local originalscore = redis.call('zscore', zsetname, member)
    local newscore
    if originalscore then
        newscore = math.floor(tonumber(originalscore))   increment
    else
        newscore = increment
    end
    redis.call('zadd', zsetname, newscore, member)
    return newscore
    ";
    return $redis->eval($luascript, [$key, $member, $increment], 1);
