Symfony Cache: a premium recipe to fast apps
summary
Symfony Cache implements PSR-6 with ready adapters for Redis, Memcached and PDO, and adds practical features: a new get(key, callable, beta) API that wraps fetch/compute/save, built-in locking and exponential early-expiry (beta default 1) to prevent stampedes, tag invalidation and chain backends, PHP/OPcache file backends and a modular serializer including igbinary serializer support. Benchmarks show PHP can fetch ~55 items/ms. Works standalone or wired by Symfony Flex; components and Contracts provide interoperable interfaces already used in system caches.
