Support for memcached and APCu is included.

Memcached
---------

[](#memcached)

```
$memcached = new Memcached();
$memcached->addServer("127.0.0.1", 11211, 50]);
$pool = new Cache\Pool\Memcached($memcached);

$cache = new Cache\Cache($pool);
```

APCu
----

[](#apcu)

```
$pool = new Cache\Pool\APCu();
$cache = new Cache\Cache($pool);
```

Blackhole
---------

[](#blackhole)

The blackhole pool is a dummy pool, which does not do any caching. It can be used on a development environment, when caching should be disabled.

```
$pool = new Cache\Pool\Blackhole();
$cache = new Cache\Cache($pool);
```

Memory
------

[](#memory)

A cache pool which uses an instance variable of the pool object as cache.

```
$pool = new Cache\Pool\Memory();
$cache = new Cache\Cache($pool);
```

Additional methods
------------------

[](#additional-methods)

Besides, the PSR standards, the Cache has implemented some useful extra methods.

### getSet

[](#getset)

getSet invokes a closure, if the key was not found inside the cache. This helps to build a linear code base, without additional conditions checking whether the key was found or not.

If the key was found, the value is returned directly, without invkoing the closure.

```
$pool = new Cache\Pool\APCu();
$cache = new Cache\Cache($pool);

$val = $cache->getSet('mykey', function() {
    // ... do some expensive calculations
    return $val;
});
```

### Grouping

[](#grouping)

If you want to invalidate a group of cache items, by only removing one key, this could be done by using the group feature.

```
$groupkey = 'mygroup';

$cache->setGrouped($groupkey, 'key1', $val1);
$cache->setGrouped($groupkey, 'key2', $val2);
$cache->setGrouped($groupkey, 'key-' . uniqid(), $val2);

$cache->delete($groupkey); // invalidates key1, key2, key-xxxx

$val = $cache->getGrouped($groupkey, 'key1'); // $val is null
```

getSetGrouped works in the same way as getSet, but with the additional group key.
