How to perform redis commands?

You can perform redis commands in three different ways:

Will call the command on the current setted server, to change server use $redis->connect() method:

$redis->some_redis_command();

Alias to the code above:

$redis->getServerConnected()->some_redis_command();

Call the command in a specific server that isn't the current connect server (but instantiated before using connect method)

$redis->getServersCollection()->getServer('some_server')->some_redis_command();
