PhpRedis bug stopping TLS encrypted cluster connection

[devsi]

• Laravel Version: 6.20.3
• PHP Version: 7.2.33
• Database Driver & Version: Redis 6.x / phpredis 5.3.2

Description:

Cannot connect to Clustered Redis instance over TLS in PhpRedis 5.3.2.

This is fixed in Laravel 7+. See here, but Laravel 6 still has this problem, needs a work around for Laravel 6.x as context doesn't exist as a configuration option. As Laravel 6 supports Redis over TLS and is still supported LTS I suspect it should be fixed in 6.x too.

Redis responds with: RedisClusterException : Error processing response from Redis node!

See the phpredis issue for more context. Fix is described in the last comment.

Steps To Reproduce:

Set up a TLS connection to a clustered redis. It seems every version of phpredis has the issue, but 5.3.2 introduces a fix. Needs to be reflected in Laravel

I've sent in a PR for this: #35370

While technically Laravel 6 is closed for new features and the new context option in Redis wasn't supported there I believe it would be good if we did. I'm closing this already. Let's see how the PR goes.

Thanks

Ah this is amazing thanks. :) I should've made the PR myself, that was rude of me! Thanks for getting that made so quick.
