Zend Framework cache Cache usage simple example

cache->cache->frontend->toArray(); $backendOptions = $config->cache->cache->backend->toArray(); $frontendName = $frontendOptions['name']; unset($frontendOptions['name']); $backendName = $backendOptions['name']; unset($backendOptions['name']); if (empty($backendOptions['cache_dir'])) { $backendOptions['cache_dir'] = CACHE_DIR; } $_cache = Zend_Cache::factory($frontendName, $backendName, $frontendOptions, $backendOptions); Zend_Registry::set('cache', $_cache); /*使用cache*/ $viewRenderer = $_cache->load('viewRenderer'); //试图从缓存加载变量 if (!$viewRenderer instanceof Something)//加载不成功 { $viewRenderer = new Something(); /*some other work*/ $_cache->save($viewRenderer, 'viewRenderer');//保存变量到换存 } /*这只是一种应用，还可以轻松缓存整页；也可将缓存存到数据库或者内存。*/ ?>
