Installation using composer

You can simply clone the repo and run composer install in the root directory. In case you want to include it elsewhere, just add the following to your composer.json:

(note: replace dev-main with a version constraint, e.g. ^4.1 - see releases for valid versions)

{
	"require": {
		"php": "^8.1",
		"chillerlan/php-cache": "dev-main"
	}
}

Installation via terminal: composer require chillerlan/php-cache

Profit!

Usage

Just invoke a cache instance with the desired CacheInterface like so:

// Redis
$redis = new Redis;
$redis->pconnect('127.0.0.1', 6379);

$cache = new RedisCache($redis);

// Memcached
$memcached = new Memcached('myCacheInstance');
$memcached->addServer('localhost', 11211);

$cache = new MemcachedCache($memcached);

// APCU
$cache = new APCUCache;

// File
$cache = new FileCache(new CacheOptions(['cacheFilestorage' => __DIR__.'/../.cache']));

// Session
$cache = new SessionCache(new CacheOptions(['cacheSessionkey' => '_my_session_cache']));

// Memory
$cache = new MemoryCache;

Methods

See: Psr\SimpleCache\CacheInterface

$cache->get(string $key, $default = null); // -> mixed
$cache->set(string $key, $value, int $ttl = null):bool
$cache->delete(string $key):bool
$cache->has(string $key):bool
$cache->clear():bool
$cache->getMultiple(array $keys, $default = null):array // -> mixed[]
$cache->setMultiple(array $values, int $ttl = null):bool
$cache->deleteMultiple(array $keys):bool
