ZendFramework中使用Cache缓存机制

ZendFramework中使用Cache缓存机制2010-10-05 CSDN博客月影传说如下图所示建立工程：

代码如下：

1.<？php
2.
3./**
4. * IndexController - The default controller class
5. *
6. * @author
7. * @version
8. */
9.
10.require_once "Zend/Controller/Action.php";
11.require_once "Zend/Cache.php";
12.require_once "Zend/Registry.php";
13.require_once "Zend/Db.php";
14.require_once "Zend/Db/Table.php";;
15.
16.class IndexController extends Zend_Controller_Action
17.{
18.public function init（）
19.{
20.$params = array （"host" => "localhost",
21. "username" => "root",
22. "password" => "root",
23. "dbname" => "mysql"）;
24.$db = Zend_Db::factory（"Pdo_Mysql", $params）;
25.Zend_Db_Table::setDefaultAdapter（$db）;
26.Zend_Registry::set（"db", $db）;
27.}
28.
29.public function indexAction（）
30.{
31.$frontendOptions = array（
32."lifeTime" => 7200, // 两小时的缓存生命期
33."automatic_serialization" => true
34.）;
35.
36.$backendOptions = array（
37."cache_dir" => "C:/tmp/" // 放缓存文件的目录
38.）;
39.
40.// 取得一个Zend_Cache_Core 对象
41.$cache = Zend_Cache::factory（"Core",
42. "File",
43. $frontendOptions,
44. $backendOptions）;
45.if（！$result = $cache->load（"myresult"）） {
46.// 缓存不命中;连接到数据库
47.$dbAdapter = Zend_Registry::get（"db"）;
48.$result = $dbAdapter->query（"SELECT * FROM user"）->fetchAll（）;
49.$cache->save（$result, "myresult"）;
50.echo "This one is from database！<br/>";
51.} else {
52.// cache hit！ shout so that we know
53.echo "This one is from cache！<br/>";
54.}
55.print_r（$result）;
56.}
57.}
