How to clear values of keys in redis

I am running two instance of my php application, one is live and one is beta. i am using redis in my live server for caching data. i am storing article category as key and article id as values.

Recently by mistake i connected my beta server with the redis and it has messed redis cache. i mean it has added some other article ids in wrong keys. so now i started getting wrong data from redis.

my question is

"is there any way to clear only values of the redis keys?"

i don't want to clear keys but only values of it.

i had gone through redis document and i found flushAll, del etc.. but based on doc it will delete my keys also it seems.

i am using predis php library to communicate with redis server.

can anybody help me to delete only values from redis server.

When you "clear" the value of a key, Redis will remove the key. Put differently, you can't have keys with no values.
