php symfony cache PHP

I'm trying to configure I'm a bit lost with I'm relatively new to this, so bear with me... I'm relatively new to this, so bear with me. I'm using PHP 8.1 with Symfony 5.4 and I've run into a question with the Symfony Cache component. I've set up a cache store using the `FilesystemAdapter`, but it doesn't seem to invalidate as expected when I update the underlying data. Here's a simplified version of my caching logic: ```php use Symfony\Component\Cache\Adapter\FilesystemAdapter; $cache = new FilesystemAdapter(); $cacheKey = 'user_data_' . $userId; // Attempt to retrieve from cache $userData = $cache->get($cacheKey, function () use ($userId) { // This function fetches fresh data from the database return fetchUserDataFromDatabase($userId); }); ``` After updating the user data in the database, I expect the next call to retrieve fresh data, but it still retrieves cached data. I've tried clearing the cache directly using: ```php $cache->delete($cacheKey); ``` However, even after this explicit deletion, the question continues. I've checked that the `fetchUserDataFromDatabase` function is indeed updating the data, but the cache seems to be serving stale data. I also tried setting a custom cache lifetime: ```php $cache = new FilesystemAdapter('', 3600); // 1 hour expiration ``` But even after the expiration time, it seems to be retaining the old value. I’m not getting any errors, but I’m confused about why the cache is not invalidating as I expect. Are there specific configurations or best practices I should follow with Symfony's cache component to ensure proper invalidation? Any insights would be greatly appreciated! I'd really appreciate any guidance on this. For context: I'm using Php on Ubuntu. My development environment is Ubuntu 20.04. Thanks in advance! I'm open to any suggestions.
