Phalcon cache

Cache\AbstractCache

Abstract Source on GitHub

This component offers caching capabilities for your application.

Event layering: cache operations can emit cache:* events from two layers. This facade fires cache:before*/cache:after* around each operation, and the underlying Storage adapter (whose eventType is "cache") also fires cache:before*/cache:after* for the same operation. If an events manager is wired into both the facade and the adapter, a single call emits the event twice (once from each object). Wire the manager into one layer only; the facade is the supported source for cache-level events (it also emits the multi-key cache:*Multiple events).
