PHP Redis Hincrby incrementing problem

The first time the request is made, Hgetall count_comment returns 58 , and then hincrBy +1 , the hGetAll expected return is count_comment 59 turned 1 . The expected incremental effect is not achieved.

Executing the same request again, Hgetall returns count_comment 1 , and then returns it again hincrBy +1 hGetAll count_comment 2 . This request hincrBy +1 is an expected increment of the implementation.

It is not clear what is the cause of the situation, for a long time did not find the reason.
Here is redis used phpredis to connect
count_commentare all string types.

I found a problem.

This is expected, you can ' t run INCR, Incrby, or Hincrby on serialized data.

When you initialize Redis, you are using the SERIALIZER format store

$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_IGBINARY);
