Redis::delete is deprecated about zend-cache HOT 9 CLOSED

Build on PHP 5.6 fails because of this. I'll try to find some time to check this out.

@gabrovex Would you like provide PR with this change? Thanks!

@gabrovex @webimpress This happens since redis extension v5.0.0. As a workaround, you can downgrade to 4.3.0. My PR should fix that behaviour.

This is actually very good point. Now just wonder if by this change we are not introducing BC Break. We do not have any requirements on Redis version so I guess we should add. Probably also we would need update tests to run with previous version of Redis (4.x, maybe even 3.x?)

@webimpress That's a very good point too. If the tests on all redis-server versions pass (no BC break), a new bugfix release could be made.
If, however, that's not the case, we would need to create a new major version (3.0.0 ?) with a requirement on the redis-server version? I don't see any alternative there, because the redis extension is already released.

@webimpress What I currently don't get, is, why the build fails on memcache for PHP 5.6 when I change a few calls in the Redis adapter.

I think because other version of service/extension is now installed. I've checked latest passing build on master and for example I see there Redis 4.0.6, your build uses Redis 5.0.4 (but I guess there could be similar reason?)

Any update on this? Its stopping us for using Zend\Cache at this point with the latest PHP version

from zend-cache.

I'd suggest adding a "conflict": {"ext-redis": ">=5.0.0"} for existing versions, and fixing this (by adding "conflict": {"ext-redis": "<4.0.0"} in a new minor.
