PHP Connect Redis Driver
I was using Predis before. But it seems that our company is using another one in the common codes. So I plan to follow that and use that one instead.
https://github.com/phpredis/phpredis#readme
Installation
> git clone https://github.com/phpredis/phpredis
> cd phpredis/
> phpize
> ./configure
> make
> sudo make install
After installation, we can try these classes as follow:

I am always using docker image to deploy my things. Actually, comparing Predis which is not an extension, the installation of extension is a little complex.
Dockerfile
#install Redis Native PHP Client
RUN yum install -y git
RUN git clone https://github.com/phpredis/phpredis
WORKDIR /install/phpredis
RUN phpize
RUN ./configure
RUN make
RUN make install
And we have to add extension configuration in php.ini
extension=iconv.so
extension=raphf.so
extension=propro.so
extension=http.so
extension=redis.so
