调用phpredis的zadd命令，score值大于999时会出现bug。
比如score值为245970，再调用zScore时获取的值就是245，好像是只能保留最高三位。
但是在另一台服务器上就正常，哪位大神有遇到类似的情况？

Okay, I found the answer by searching on the Internet, asking and answering it myself.
The first solution, https://github.com/phpredis/phpredis/commit/83f3440b889c79291d369d83ce..., modify the source code and then compile and install.
The second option is git clone -b php-numencode https://github.com/nicolasff/phpredis.git. Re-download the fixed version of phpredis installation.
