<?php
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/' );
/*
配置文件config.ini:
[cache]

*/
/*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
}
/*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。*/

希望本文所述对大家基于Zend Framework框架的PHP程序设计有所帮助。
