Issues with latest phpredis breaking RedisTaggedCache

[scottasmith]

Laravel Version

11.9

PHP Version

Docker/Linux php:8.3.7-fpm-bookworm

Database Driver & Version

N/A

Description

OS: Docker / Linux
PHP: 8.3.7
Laravel: 11.9
Redis server: 7.4
phpredis: 6.1.0

The latest version of phpredis (6.1.0) has been changed to use an unsigned 64-bit cursor.
See phpredis/phpredis#2458 and phpredis/phpredis#2462.

There is a bug report here phpredis/phpredis#2562, but this is intended behaviour going forward.

This means it breaks tagged caching on redis.

This is the line causing the issue with the latest version of the extension: https://github.com/laravel/framework/blob/master/src/Illuminate/Cache/RedisStore.php#L298

Also this is breaking the entries https://github.com/laravel/framework/blob/master/src/Illuminate/Cache/RedisTagSet.php#L40

Steps To Reproduce

To recreate I did composer create-project laravel/laravel:^11 . in a new directory. Then I added a docker-compose.yml and Dockerfile to it along with some examples in routes/web.php.

The problem is shown in this repo: https://github.com/scottasmith/laravel-phpredis-problems

If you clone it, run docker compose up -d and navigate to the urls in https://github.com/scottasmith/laravel-phpredis-problems/blob/main/routes/web.php.

• http://localhost:8001/not-working shows phpredis and how laravel currently works
• http://localhost:8001/working shows phpredis and how laravel should work (with this version)
• http://localhost:8001/laravel-failing demonstrates that the flush isn't working
• http://localhost:8001/laravel-entries shows its not getting the entries for the flush

@taylorotwell Could this fix also be backported to Laravel 10.x ?
