Way back in 2011, I created Beryllium\CacheBundle
for Symfony 2. It got a bit of traction, but superior options soon appeared, and then PSR-6 landed and promised a whole new world of caching. PSRs, or "PHP Standard Recommendations", are a group of framework interoperability interfaces provided by the PHP Framework Interoperability Group (FIG).
I wasn't exactly a fan of PSR-6.
The PSR was well-engineered, but it seemed like overkill for my projects. And on top of that, I was no longer working on the project that had needed caching in the first place.
