我希望codeigniter回显php错误，而不是500个内部错误

I have currently set my Codeigniter root index.php's environment variable to development.

我现在已经设置了Codeigniter根索引。php的环境变量。

And I haven't also enabled tiny URL mode.

我还没有启用小URL模式。

I don't like to check /var/log/apache2/error.log every night and day!

我不喜欢检查/var/log/apache2/error。日日夜夜的记录!

Want my PHP errors back to the page. 500 Internal error is really the *HARD*est method that can be used to show the error.

希望PHP错误返回页面。500个内部错误实际上是可以用来显示错误的最硬的方法。

Note that we are working on an Ubuntu 12.04 LTS server with default config.

注意，我们正在使用默认配置的Ubuntu 12.04 LTS服务器。

As mentioned in the comment I'm doubtful that this is CodeIgniter's issue. It's more likely that you simply have display_errors set to off in your php.ini.

正如在评论中提到的，我怀疑这是不是CodeIgniter的问题。在php.ini中，更有可能只是将display_errors设置为off。

If I remember correctly, CI's index.php contains a call to ini_set('error_reporting', ..); to change the default behaviour anyway, so you could always look in there first and see what's going on.

如果我没记错的话，是CI索引。php包含对ini_set('error_reporting'， .. .)的调用;为了改变默认的行为，你可以先看看里面发生了什么。

Just had a look, here's the default:

看一下，这里是默认值:

/*
|---------------------------------------------------------------
| PHP ERROR REPORTING LEVEL
|---------------------------------------------------------------
|
| By default CI runs with error reporting set to ALL.  For security
| reasons you are encouraged to change this when your site goes live.
| For more info visit:  http://www.php.net/error_reporting
|
*/
    error_reporting(E_ALL);

If you simply add under there ini_set('display_errors', 1);, it should start working just fine. Obviously the best bet would be to add a switch for your environment to set these variables, I'm not sure why it's not like that already, but here's an example:

如果您只是在那里添加ini_set('display_errors'， 1);显然，最好的办法是为您的环境添加一个开关来设置这些变量，我不确定为什么不是这样，但是这里有一个例子:

if (defined('ENVIRONMENT'))
{
    switch (ENVIRONMENT)
    {
        case 'development':
            error_reporting(E_ALL);
            ini_set('display_errors', 1);
            break;
        case 'production':
            error_reporting(0);
            ini_set('display_errors', 0);
            break;
    }
}

Just add the following in your index.php, in the development environment case:

只需在索引中添加以下内容。php，在开发环境中:

case 'development':
 error_reporting(E_ALL);
 ini_set('display_errors', 'On');

EDIT: as Rudi Visser said, you could fix it changing your php.ini. I prefer to fix it here, so whenever I download the project (my laptop, my office pc or a computer I borrow in an emergency, I don't need to change the php.ini configuration)

编辑:正如Rudi Visser所说，你可以修改你的ph .ini。我更喜欢在这里修改它，所以每当我下载项目(我的笔记本电脑，我的办公电脑或者我在紧急情况下借来的电脑)时，我都不需要修改php。ini配置)

I had the same problem the only thing i got from codeigniter was only an 500 Internal error.(my old projects and a clean install did the same) But the interesting part is that my non CI projects still worked that contained mostly php.

我也有同样的问题我从codeigniter得到的唯一结果就是500个内部错误。(我以前的项目和干净的安装都是一样的)但有趣的是，我的非CI项目仍然在运行，主要包含php。

The tip to write out the error with

要写出错误的提示。

ini_set('display_errors', 'On' / ,1)

Solved my problem for some reason i didn't have the rights to read the codeigniter core files.

由于某些原因，我解决了我的问题，我没有权利阅读codeigniter核心文件。

Adding ' +r ' to the files fixed the problem.

在文件中添加“+r”解决了这个问题。
