Cachearium 是一个用于 PHP 应用的高级缓存框架，具有简单和快速的特点。

• recursive cache system, all the nested russian dolls you ever wanted
• easy to integrate with your existing classes
• key based cache expiration, no more headaches to invalidate stuff
• multiple dependencies
• lifetime expiration, because stuff rots
• low level cache storage access, when you want to go raw
• lots of examples and tests ready to copy/paste
• variable fragments for things that are almost the same but not quite
• pluggable backend modules: RAM, Memcached, Filesystem and you can add your own
• detailed logs for profiling and debugging, and also see what is cached live in your webpage

示例代码：

$data = 'xxxx';     // store  $cache = CacheAbstract::factory('your backend');  $cache->store($data, new CacheKey('Namespace', 'Subname'));     // get it later  try {       $data2 = $cache->get(new CacheKey('Namespace', 'Subname'));      // $data2 == 'xxxx';  }  catch (NotCachedException($e)) {      // handle not cached  }     // store new value with automatic invalidation  $data = 'yyy';  $cache->store($data, new CacheKey('Namespace', 'Subname'));
