直接用require_once '../models/Message.php';  报错
//此方法能解决路径不对的错误
 方法1   require_once  dirname(dirname(__FILE__)).'/models/Message.php';

方法2   require_once APPLICATION_PATH.'/models/Message.php';

原因如下：

echo __FILE__ ; // 取得当前文件的绝对地址，结果：D:\www\test.php
echo dirname(__FILE__); // 取得当前文件所在的绝对目录，结果：D:\www\
echo dirname(dirname(__FILE__)); //取得当前文件的上一层目录名，结果：D:\
 
 
<?php
 require_once '../models/Message.php';
 //此方法能解决路径不对的错误
  //require_once  dirname(dirname(__FILE__)).'/models/Message.php';
 class IndexController extends Zend_Controller_Action

 //这是初始化函数
     public function init()
