php - codeigniter (CI) 的 session 问题

Question

我在使用 codeigniter 开发的 live 上遇到 php session 错误

A PHP Error was encountered

Severity: Warning

Message: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/userts4m/public_html/development/relatioweb/admin/index.php:1)

Filename: Session/Session.php

Line Number: 140

Backtrace:

File: /home/userts4m/public_html/development/relatioweb/application/admin/controllers/User.php
Line: 9
Function: __construct

File: /home/userts4m/public_html/development/relatioweb/admin/index.php
Line: 293
Function: require_once

在 localhost 工作很好。但是当我在服务器上上传时，我们面临着这个问题。

我该怎么办...

Answer 1

有两种解决方案可以解决此问题。

有时这个错误是由于框架配置错误导致的， 转到文件夹 applications/config 并打开 config.php 像这样在文件的开头写这个

<?php

  if (!defined('BASEPATH')) exit('No direct script access allowed');
    ob_start();
    /* Remaining Part Of your file
     .........................................
   */

另一种解决方法是在类的构造函数中写ob_start() 像这样:

<?php

 if (!defined('BASEPATH')) exit('No direct script access allowed');
   class Your_Controller extends CI_Controller {
     public function __construct() {
       parent::__construct();
       ob_start();
     }
   }
