本节分享下，zf中zend_cache的一个例子。
代码如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 | <?php/*** Zend Cache用法举例* edit by www.jb200.com*/require 'Zend/Loader.php';Zend_Loader::loadClass('Zend_Cache');Zend_Loader::loadClass('Zend_Config');Zend_Loader::loadClass('Zend_Registry');$config = new Zend_Config_Ini('configsecr/config.ini');define('CACHE_DIR',FDROOT.'/'.'tmp/');/* config.ini [cache]cache.needcache=1cache.frontend.name=Corecache.frontend.lifetime=7200cache.frontend.automatic_serialization=1cache.backend.name=File*//*选项参考手册*//*建立cache对象*/$frontendOptions = $config->cache->cache->frontend->toArray();$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}/*使用Zend Cache还可以轻松缓存整页；且可将缓存存到数据库或者内存。大家好好研究下哦。*/?> |
