如何使用Memchached后端和Zend Framework有选择地清除缓存(使用标签或其他选项) [英] How to selectively clear cache (using tags or other option) with Memchached backend and Zend Framework

问题描述

我们在Web项目中使用Memcached和Zend Framework.现在，我们需要使用 Zend_Cache API .

We use Memcached and Zend Framework in our web project. Now, we need to clean cache selectively using tags as specified in Zend_Cache API.

不幸的是， memcached不支持标签.

我发现了以下解决方法:

I have found these workarounds:

• Memcached-tag项目.有人测试过吗?如何使用Zend实施?
• 像此问题中一样使用通配符，但似乎有点令人困惑，透明度较低，难以理解用Zend实施.
• 使用此实现或

• Memcached-tag project. Has anybody tested it? How to implement it with Zend?
• Use wildchards like in this question, but it seems a bit confusing, less transparent and harder to implement with Zend.
• Use this implementation or this one, for supporting tags in Memcached, beeing aware of the drawbacks.
• Any other option?

推荐答案

您是对的. Memcache不支持标签.

You're right. Memcache don't support tags.

您可以使用另一个键值来实现memcache的标签.

You can use another key-value to implement tag for memcache.

EX:

$this->objCache->save($arrResults, $strKey,array($strMyTag),$intCacheTime) // note : array($strMyTag) don't work for Memcache

MemcacheTag::setTag($strKey, $strMyTag) // our work around

关于setTag方法& MemcacheTag:

About setTag Method & MemcacheTag:

function setTag($strKey,$strTag){

    $arrKey  = $cacheOjb->get($strTag);

    $arrKey[]= $strKey; 

}

function deleteCacheWithTag($strTag){

    $arrKey  = $cacheOjb->get($strTag);

    foreach ($arrKey as $strKey){

       $objCache->delete($strKey);

    }

}

此解决方法非常简单，适用于我的项目.

This work around is quite simple and it works for my projects.
