DB 4 with persistent connection

$cache = new Cache( '/your/path/to/cache-file.db4', 'db4');

$yorObject = new YourObjectYouWantToPutInCache();$yourObjectIdentifier = 'key:you:want';

// Check if your object is in the cache.// You also can ignore it, and let the CacheDba do it for you.if (false == $cache->has($yourObjectIdentifier)) { $cache->delete($yourObjectIdentifier);}

$cache->put($yourObjectIdentifier, $yorObject);

// Than somewhere at your project.$cache->get($yourObjectIdentifier);

Sweep in action// For the garbage collection you can // create for example an cron-job starting once a day// or please use the DBA-Cache-Monitor GUI.$sweep = new Sweep($cache);

// clean all entries$sweep->all();

// or clean old entries – from now$sweep->old();

// or flush the whole storage!$sweep->flush();
