Zend_Session:必须在任何输出发送到浏览器之前启动会话 [英] Zend_Session: Session must be started before any output has been sent to the browser

问题描述

我以前遇到过这个问题，但我不记得如何解决它.我已经创建了一个简单的骨架(不能再简单了)控制器，我只是想向浏览器回显一些东西，我收到了这条消息:

I've run into this issue before, but I can't remember how to solve it. I have created a bare bones (can't get any simpler) controller, and am just trying to echo something to the browser, and I am getting this message:

Fatal error: Uncaught exception 'Zend_Session_Exception' with message 'Session must be started before any output has been sent to the browser ...

这是我的整个控制器.它显示成功"，但也显示错误消息.如何让该错误消息静音，以便我可以简单地向浏览器回显某些内容?

Here's my entire controller. It's displaying 'success', but it also displays the error message. How can I silence that error message so I can simply echo something to the browser?

<?php

class CacheController extends Zend_Controller_Action
{
    public function clearAction()
    {
        $this->_helper->layout->disableLayout();
        $this->_helper->viewRenderer->setNoRender();
        try {
            $result = Model_Cache::emptyCache(array('foobar'=>1));

            if ($result['status'] == true) {
                echo 'Success';
            } else {
                echo 'Error: ' . $result['message'];
            }
        } catch (Exception $e) {
            echo 'Error: ' . $e->getMessage();
        }
    }
}

推荐答案

出于某种原因，我试图在应用程序完成引导后在我的 index.php 文件中设置一些会话变量.不知道为什么这之前没有引起问题，但是当我从我的 index.php 中删除它时，它起作用了.

For some reason, I was trying to set some session variable in my index.php file after the application had finished bootstrapping. Not sure why this didn't cause a problem before, but when I removed this from my index.php, it worked.

$userSession = new Zend_Session_Namespace('Auth');
$userSession->forcePasswordChange = false;
