Caching

maplephp/cache implements both PSR-6 (CacheItemPoolInterface) and PSR-16 (CacheInterface). The Cache wrapper provides the PSR-16 API around any PSR-6 handler.

Basic usage

use MaplePHP\Cache\Cache;
use MaplePHP\Cache\Handlers\FileSystemHandler;
use MaplePHP\Core\App;

$cache = new Cache(new FileSystemHandler(App::get()->dir()->cache()));

// Read (returns $default on miss)
$value = $cache->get('my-key', null);

// Write with TTL in seconds
$cache->set('my-key', $computedResult, 3600);

// Check existence
if ($cache->has('my-key')) { ... }

// Delete
$cache->delete('my-key');

// Clear all
$cache->clear();

Handlers

Handler	Description
FileSystemHandler	Writes cache files to a directory. Pass App::get()->dir()->cache() as the path.
MemcachedHandler	Uses a \Memcached instance.

Swap handlers without changing any other code:

use MaplePHP\Cache\Handlers\MemcachedHandler;

$memcached = new \Memcached();
$memcached->addServer('127.0.0.1', 11211);

$cache = new Cache(new MemcachedHandler($memcached));

The Cache class and all callers remain unchanged. Only the handler construction changes.
