AMPHP is a collection of event-driven libraries for PHP designed with fibers and concurrency in mind. amphp/cache specifically provides a cache interface and multiple implementations of it.

This package can be installed as a Composer dependency.

composer require amphp/cache

<?php

namespace Amp\Cache;

interface Cache
{
    public function get(string $key): mixed;

    public function set(string $key, mixed $value, int $ttl = null): void;

    public function delete(string $key): ?bool;
}

Cache implementation that just ignores all operations and always resolves to null.
