Codeigniter显示空白页而不是错误消息 [英] Codeigniter displays a blank page instead of error messages

问题描述

我使用Codeigniter，而不是错误消息，我只是得到一个空白页。有没有办法显示PHP错误消息？当我没有收到任何反馈时，很难调试。

I'm using Codeigniter, and instead of error messages I'm just getting a blank page. Is there any way to show PHP error messages instead? It's very hard to debug when I get no feedback.

我的环境是Ubuntu的Apache。

My environment is Ubuntu with Apache.

推荐答案

由于目前没有任何解决方案能为您效劳，请尝试以下方法：

Since none of the solutions seem to be working for you so far, try this one:

ini_set('display_errors', 1);

http://www.php.net/manual/en/errorfunc.configuration.php#ini.display-errors

这显式地告诉PHP 显示错误。

This explicitly tells PHP to display the errors. Some environments can have this disabled by default.

这是我的环境设置在 index.php 中的样子：

This is what my environment settings look like in index.php:

/*
 *---------------------------------------------------------------
 * APPLICATION ENVIRONMENT
 *---------------------------------------------------------------
 */
define('ENVIRONMENT', 'development');
/*
 *---------------------------------------------------------------
 * ERROR REPORTING
 *---------------------------------------------------------------
 */
if (defined('ENVIRONMENT'))
{
    switch (ENVIRONMENT)
    {
        case 'development':
            // Report all errors
            error_reporting(E_ALL);

            // Display errors in output
            ini_set('display_errors', 1);
        break;

        case 'testing':
        case 'production':
            // Report all errors except E_NOTICE
            // This is the default value set in php.ini
            error_reporting(E_ALL ^ E_NOTICE);

            // Don't display errors (they can still be logged)
            ini_set('display_errors', 0);
        break;

        default:
            exit('The application environment is not set correctly.');
    }
}
