This seems to be troubling a lot of people, so after debugging Zend’s code, I’ll post the solution on how to change the cache directory of zend_cache.
I’m using the below code in my zend framework bootstrap to setup Zend_Cache for caching to files.
$frontend= array('lifetime' => 7200, 'automatic_serialization' => true); $backend= array('cache_dir' => DIR_CACHE); $cache = Zend_Cache::factory('core', 'File', $frontend, $backend); //assign to registry $registry = Zend_Registry::getInstance(); $registry->cache = $cache;
I need to be able to override the cache directory at a later time and when I’m ready to use the cache in the application, I reference this Zend_Cache like below, which returns an object of Zend_Cache_Core, which you cannot call setCacheDir() on. We must first get the backend component, then call the method as below.
$cache = Zend_Registry::get('cache'); //set the new cache directory $cache->getBackend()->setCacheDir($cacheDirectory);
