PHP redis hIncrBy 递增出现问题
第一次请求的时候，hGetAll返回的count_comment是58，然后hincrBy +1后再hGetAll，返回的count_comment预期为59却变成1了。没有实现预期递增效果。
再次执行同样请求，hGetAll返回的count_comment是1，然后hincrBy +1后再hGetAll，返回的count_comment是2了。这次请求hincrBy +1是实现的预期递增。
不太清楚是什么情况造成，找了好久没找到原因。
这里的redis中使用phpredis来连接count_comment都是string类型。

我找到问题了
This is expected, you can't run INCR, INCRBY, or HINCRBY on serialized data.
初始化redis时，使用的是SERIALIZER格式下存储
<code>$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_IGBINARY);</code>
