KISS (Keep It Simple Stupid) PSR (PHP Standards Recommendations) 类。

安装

composer require arnapou/psr-cache

packagist 👉️ arnapou/psr-cache

示例 PSR-6 缓存

KISS,这里我们只有 PSR-16 Simple 缓存的 PSR-6 适配器。

注意,您可以注入自己的 PSR-20 Clock 接口。

$cache = new \Arnapou\Psr\Psr6Cache\CacheItemPool(
    psr16SimpleCache: $psr16SimpleCache, 
    defaultTtl: 900, 
);
$item = $cache->getItem('my-key');
$item->set('my-value');
$item->expiresAfter(300);
$cache->save($item);

示例 PSR-16 Simple Cache

我没有从 PSR 实现的一件事是 PSR 键字符限制。

因为我在过去 12 年中从未见过需要这种情况的案例。

实施的技术限制只有(例如 memcached)。

实现。

use Arnapou\Psr\Psr16SimpleCache;

// For runtime, full memory
$cache = new Psr16SimpleCache\ArraySimpleCache(defaultTtl: 900);

// Flat file cache with custom serializer and PSR-20 Clock Interface
$cache = new Psr16SimpleCache\FileSimpleCache(path: '/path/of/cache', defaultTtl: 900);

// Memcached cache with custom serializer and PSR-20 Clock Interface
$cache = new Psr16SimpleCache\MemcachedSimpleCache($memcached);

// Redis cache with custom serializer and PSR-20 Clock Interface
$cache = new Psr16SimpleCache\RedisSimpleCache($redis);

// Does nothing at all
$cache = new Psr16SimpleCache\NullSimpleCache();

装饰器。

use Arnapou\Psr\Psr16SimpleCache\Decorated;

// Helps to reduce I/Os on decorated cache by keeping in memory the values already retrieved
$cache = new Decorated\RuntimeSimpleCache($decorated);

// Helps to isolate keys in "namespaces" for instance
$cache = new Decorated\PrefixSimpleCache($decorated, 'some:prefix');

// Forces the ttl to be in the range wanted to avoid silly TTLs
$cache = new Decorated\TtlRestrictedSimpleCache($decorated, ttlMin: 60, ttlMax: 3600);

// Avoid any writing in that cache
$cache = new Decorated\ReadonlySimpleCache($decorated, throwException: true);
