PSR-16 - Simple Cache

To add support for PSR-16 Simple Cache, require the PSR.

composer require psr/simple-cache

Usage

<?php

use SonsOfPHP\Component\Cache\Adapter\ApcuAdapter;

$pool = new ApcuAdapter();

All Adapters implement Psr\Cache\CacheItemPoolInterface

PSR-16 Simple Cache Wrapper

<?php

use SonsOfPHP\Component\Cache\Adapter\ApcuAdapter;
use SonsOfPHP\Component\Cache\SimpleCache;

$pool = new ApcuAdapter();
$cache = new SimpleCache($pool);

SimpleCache implements Psr\SimpleCache\CacheInterface.

Setting up a multi layer cache

<?php

use SonsOfPHP\Component\Cache\Adapter\ArrayAdapter;
use SonsOfPHP\Component\Cache\Adapter\ApcuAdapter;
use SonsOfPHP\Component\Cache\Adapter\ChainAdapter;

$pool = new ChainAdapter([
    new ArrayAdapter(),
    new ApcuAdapter(),
]);

The ChainAdapter will read from all pools and return the first result it finds. So in the above example, if the cache item is not found in ArrayAdapter, it will look for it in the ApcuAdapter pool.

The ChainAdapter will also write to and delete from all pools.
