这篇文章给大家介绍Zend Framework中FlashMessenger如何使用，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。
FlashMessenger简单用法：
在helper_demo1项目的基础上
新增/helper_demo1/application/controllers/UserController.php
<?php
class UserController extends Zend_Controller_Action
{
protected $_flashMessenger = null;
public function init()
{
$this->_flashMessenger =
$this->_helper->getHelper('FlashMessenger');
$this->initView();
}
public function registerAction()
{
$this->_flashMessenger->addMessage('xxxxx,Welcome!');
$this->_helper->redirector('regtips');
}
public function regtipsAction()
{
$this->view->messages = $this->_flashMessenger->getMessages();
}
}新增/helper_demo1/application/views/scripts/user/regtips.phtml
