Caching with PSR-6 at PHP Valencia

Caching with PSR-6 at PHP Valencia

In this talk we will explain what PSR-6 is, why it is designed like it is, and how to use it. From the provided interfaces, the virtual package on Packagist.org, to the implementations available. Everything will be explained for both beginners and more experienced developers. We will dive into implementations, cache stampede protection, all using libraries we can find on Packagist.org. We will also show how to start using it today in our current applications by using adapters. The entire talk will be accompanied with code samples and live demos, showing both working and failing caching systems.
