本文實例講述了Zend Framework框架中實現(xiàn)Ajax的方法。分享給大家供大家參考，具體如下：
開發(fā)平臺：Windows XP SP2
測試平臺：FreeBSD 7.0
開發(fā)工具：Netbeans 6.1
使用框架：Zend Framework 1.5.2
數(shù)據(jù)庫： MySQL 5.0.51a
所需的數(shù)據(jù)庫表和ZF相關(guān)目錄以及文件：
一、表：

mysql> select * from news;+----+-------+---------------------+| id | title | add_time| +----+-------+---------------------+| 22 | rot | 2008-01-04 00:00:00 || 23 | aaa | 2008-01-04 00:00:00 || 24 | rot | 2008-01-04 00:00:00 || 29 | dfeew | 2008-02-27 00:00:00 || 26 | jesse | 2008-02-27 00:00:00 || 27 | andle | 2008-02-27 00:00:00 || 28 | andle | 2008-02-27 00:00:00 |+----+-------+---------------------+ |
二、目錄：
三、相關(guān)文件：
1.index.php //入口文件
2.TestDbCon.phhp //數(shù)據(jù)庫連接文件
3.News.php //抽象出來的數(shù)據(jù)庫表文件
4.TestController.php //控制器
5.ajax.phtml //客戶操作頁面，包含生成XMLHttpRequest對象，發(fā)ajax請求，處理請求，取回服務(wù)器返回值等
6.get-ajax.phtml //最后根據(jù)由服務(wù)器取回的數(shù)據(jù)生成頁面元素
相關(guān)文件內(nèi)容：
1.index.php //入口文件

6.get-ajax.phtml //最后根據(jù)由服務(wù)器取回的數(shù)據(jù)生成頁面元素
希望本文所述對大家基
- <?php
- foreach($this->rowSet as $row){
- echo "<div>";
- echo "<ul>";
- echo "<li>";
- echo "id=".$row->id." title=".$row->title." add_time=".$row->add_time;
- echo "</li>";
- echo "</ul>";
- echo "</div>";
- }
- echo $this->sid;
- ?>
于Zend Framework框架的PHP程序設(shè)計有所幫助。
