Based on php-dba-cache a have writen a "Zend_Cache_Backend_Dba" class. The php-dba-cache uses the database (dbm-style) abstraction layer to cache your objects, strings, integers or arrays. Even instances of SimpleXMLElement can be puted to the cache. I just wrote the Class "Zend_Cache_Backend_Dba" for my company, and it works fine. More information about php-dba-cache you can find at https://github.com/gjerokrsteski/php-dba-cache
I allso can see the "Zend_Cache_Backend_Dba" class at https://github.com/gjerokrsteski/… for inspection.
