implementing PHP 8.2 Session Management when Using Redis for Storage
I'm experimenting with I need some guidance on I'm experiencing unexpected behavior when trying to manage sessions in PHP 8.2 with Redis as the session handler... My application is built on Laravel 9, and I'm using the `predis/predis` library to interact with Redis. The sessions are supposed to expire after 30 minutes of inactivity, but some users report experiencing sessions that continue for much longer than expected. I've configured Redis as follows in my `config/session.php`: ```php 'session' => [ 'driver' => 'redis', 'lifetime' => 30, 'expire_on_close' => false, 'encrypt' => false, 'connection' => 'default', ], ``` In the Redis configuration, I have the default expiry set to 1800 seconds. However, when debugging, I noticed that the `phpinfo()` output shows the session garbage collection probability settings as follows: ```ini session.gc_probability = 1 session.gc_divisor = 100 ``` This results in a 1% chance of garbage collection running, which seems rather low. I tried increasing the probability to 10, but it didn’t seem to have any effect on session expiration. The behavior is inconsistent; while some sessions expire as expected, others linger well beyond the intended lifetime. I'm also using middleware to regenerate the session ID on user login to prevent fixation attacks, which might be contributing to the question. I’ve checked the Redis keys for the sessions, and they seem to be expiring correctly according to Redis TTL commands, but the PHP session handling doesn’t seem to be honoring these expirations. Any suggestions on how to ensure that sessions expire correctly or what could be causing this inconsistency in session management? The Laravel version is 9.52 and Redis is 6.0.9. Also, I want to follow best practices for session management in this scenario. Should I be considering any specific patterns or configurations with Laravel and Redis in PHP 8.2? For context: I'm using Php on Windows 10. I'd love to hear your thoughts on this. This issue appeared after updating to Php 3.10. Any suggestions would be helpful. What's the best practice here?
