Codeigniter在虚拟主机错误404中

Question

codeigniter 3.0.2

关于我的localhost env config

  

PHP 5.2+ apache 2.4 +

打印我的本地主机CI日志：

一切正常，一切正常！

关于虚拟主机env config

  

PHP 5.2+ Apache 2.2 +

打印虚拟主机CI日志：

INFO - 2015-11-09 20:22:56 --> Config Class Initialized
INFO - 2015-11-09 20:22:56 --> Hooks Class Initialized
DEBUG - 2015-11-09 20:22:56 --> UTF-8 Support Enabled

INFO - 2015-11-09 20:22:56 --> Security Class Initialized
DEBUG - 2015-11-09 20:22:56 --> Global POST, GET and COOKIE data sanitized
INFO - 2015-11-09 20:22:56 --> Input Class Initialized
INFO - 2015-11-09 20:22:56 --> Language Class Initialized
ERROR - 2015-11-09 20:22:56 --> 404 Page Not Found: /index

报告404页面未找到，一切都是404！

为什么呢？比较它们，我发现 Loader Class Initialized 发生此错误。

我也试试$ config [＆＃39; uri_protocol＆＃39;]，使用

• PATH_INFO

• REQUEST_URI

• QUERY_STRING

它在我的本地主机中工作，但在虚拟主机中都是404，所以它无法获得它。

请帮帮我。

Answer 1

使用CodeIgniter 3.0.x时，所有控制器文件名都必须以大写字母开头。确保您的文件以这种方式命名。

例如，在/application/controllers/中，文件a_controller.php必须命名为A_controller.php

同样重要的是控制器文件中类名的首字母大写字母的规则。例如，这是错误的

class a_controller extends CI_Controller {

这是正确的。

class A_controller extends CI_Controller {
