Php script does not find class Redis

[fbartolom]

When I run the script in the example I get an error by which class Redis (whether or not preceeded by ) is not found. I installed the whole by composer but the example misses any include in the file. How may I have the script find the Redis class?

Redis has to be activated in your php config files. (e.g. php.ini in /etc/php).
You have an extension named "redis.so", uncomment it to enable Redis in php
