Zend 框架清除缓存

Zend Framework Clearing Cache(Zend 框架清除缓存)

问题描述

我正在使用此代码在 zend 框架中缓存数组:

I'm using this code to cache an array in zend framework :

$frontendOptions = array(
    'lifetime' => 24 * 3600 * 7, // cache lifetime of 7 day
    'automatic_serialization' => true
);

$backendOptions = array(
    // Directory where to put the cache files
    'cache_dir' => APPLICATION_PATH .'/../tmp'
);

// getting a Zend_Cache_Core object
$cache = Zend_Cache::factory('Core',
    'File',
    $frontendOptions,
    $backendOptions);

$CacheName = ('VOUCHER_MANAGEMENT');

$CacheResult = $cache->load($CacheName);

if($CacheResult === false)
    //make cache
else 
    //use cache

现在如何手动清除缓存?

Now how can I clear the cache manually?

推荐答案

根据文档 一次调用 remove() 方法就足够了，即删除特定的缓存项:

According to the documentation a single call of the remove() method would suffice, i.e. to remove a specific cache item:

$cache->remove($CacheName);

如果要清理过时的缓存项，则调用clean()方法:

If you want to clean the outdated cache items, then call the clean() method:

$cache->clean(Zend_Cache::CLEANING_MODE_OLD);

要删除缓存中的所有项目:

To remove all items in the cache:

$cache->clean(Zend_Cache::CLEANING_MODE_ALL);
