Additional context

I did try writing a test. Unfortunately, it kept failing on PHP 7.0 and 7.1. I stuffed about with it for a little while but I think it's time for bed 🥱

Looks good - thanks. We should be able to do a patch release soon.

Also, thanks for trying to write the test - it was almost right. I believe the problem was that when writing test data, you used self::PREFIX . ":$namespace" without accounting for how the SDK also adds its own prefix to Redis keys. The default for that is "launchdarkly" so it would really be self::PREFIX . "launchdarkly:$namespace". We'll add the test before releasing - and we should've had a test for this kind of configuration in the first place.
