本文實(shí)例講述了Zend Framework緩存Cache用法。分享給大家供大家參考，具體如下：

<?php
require &#39;Zend/Loader.php&#39;;
Zend_Loader::loadClass(&#39;Zend_Cache&#39;);
Zend_Loader::loadClass(&#39;Zend_Config&#39;);
Zend_Loader::loadClass(&#39;Zend_Registry&#39;);
$config = new Zend_Config_Ini(&#39;configsecr/config.ini&#39;);
define(&#39;CACHE_DIR&#39;,FDROOT.&#39;/&#39;.&#39;tmp/&#39;);
/*
配置文件config.ini：
[cache]
cache.needcache=1
cache.frontend.name=Core
cache.frontend.lifetime=7200
cache.frontend.automatic_serialization=1
cache.backend.name=File
*/
/*選項(xiàng)參考手冊(cè)*/
/*建立cache對(duì)象*/
$frontendOptions = $config->cache->cache->frontend->toArray();
$backendOptions = $config->cache->cache->backend->toArray();
$frontendName = $frontendOptions[&#39;name&#39;];
unset($frontendOptions[&#39;name&#39;]);
$backendName = $backendOptions[&#39;name&#39;];
unset($backendOptions[&#39;name&#39;]);
if (empty($backendOptions[&#39;cache_dir&#39;]))
{
 $backendOptions[&#39;cache_dir&#39;] = CACHE_DIR;
}
$_cache = Zend_Cache::factory($frontendName, $backendName, $frontendOptions, $backendOptions);
Zend_Registry::set(&#39;cache&#39;, $_cache);
/*使用cache*/
$viewRenderer = $_cache->load(&#39;viewRenderer&#39;); //試圖從緩存加載變量
if (!$viewRenderer instanceof Something)//加載不成功
{
 $viewRenderer = new Something();
 /*some other work*/
 $_cache->save($viewRenderer, &#39;viewRenderer&#39;);//保存變量到換存
}
/*這只是一種應(yīng)用，還可以輕松緩存整頁(yè)；也可將緩存存到數(shù)據(jù)庫(kù)或者內(nèi)存。*/
?>

希望本文所述對(duì)大家基于Zend Framework框架的PHP程序設(shè)計(jì)有所幫助。
