Symfony version(s) affected

6.3.5

Description

Redis::mget can return false when no keys are provided. phpredis/phpredis#1810

This is annoying because the signature says mget(): \Redis|array, but it's actually mget(): \Redis|array|false.

Redis6Proxy::mget has the correct signature, but it doesn't handle the possible false.

How to reproduce

Set up PHPRedis v6 and do Redis6Proxy::mget([])

Possible Solution

Return [] if false.

Additional Context

IMO this is a bug in the module, but it's a bug since 2020.
