php 如何配置 Codeigniter 报告所有错误？

How to configure Codeigniter to report all errors?

提问by AppleGrew

I had a line - $autoload['libraries'] = array('database');, in CI's autoload.php. Because of this I was getting a blank page. When I removed the 'database', option then I started getting the output.

我有一条线 - $autoload['libraries'] = array('database');，在 CI 的autoload.php. 因此，我得到了一个空白页。当我删除'database', 选项时，我开始获取输出。

Now my question is not how to configure the database, but how to configure CI to speak its mind. When 'database'was enabled all I got was a complete blank page. No error in php log, no error in Apache log, no error in CI log. In PHP I have set E_ALL. In my CI config I have set log_thresholdto 4, i.e. all messages should be logged. What more do I need to do?

现在我的问题不是如何配置数据库，而是如何配置CI来说出它的想法。当'database'启用时，我得到的只是一个完整的空白页面。php日志没有错误，Apache日志没有错误，CI日志没有错误。在 PHP 中，我已经设置了E_ALL. 在我的 CI 配置中，我已设置log_threshold为4，即应记录所有消息。我还需要做什么？

It depends on your version of CI. For < 2.x edit the top level index.php and adjust the error_reporting function to use E_ALL"

这取决于您的 CI 版本。对于 < 2.x 编辑顶级 index.php 并调整 error_reporting 函数以使用 E_ALL”

error_reporting(E_ALL);

For >= 2.x edit the top level index.php and make sure ENVIRONMENT is set as:

对于 >= 2.x 编辑顶级 index.php 并确保 ENVIRONMENT 设置为：

define('ENVIRONMENT', 'development');

which sets the error_reporting to E_ALL.

它将 error_reporting 设置为 E_ALL。

Create a .htaccess file in your webroot with the following content

使用以下内容在您的 webroot 中创建一个 .htaccess 文件

php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on
php_flag log_errors on
php_flag ignore_repeated_errors off
php_flag ignore_repeated_source off
php_flag report_memleaks on
php_flag track_errors on
php_value error_reporting -1
php_value log_errors_max_len 0

Hopefully that should enable your logs.
Make sure to set the values to offand reporting to 0on your production server :)

希望这应该可以启用您的日志。
确保在您的生产服务器上将这些值设置为关闭并报告为0:)

Following environment settings would gonna force PHP to display errors as they occur:

以下环境设置将强制 PHP 在错误发生时显示：

• 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.');
  }
  

  }

• 应用环境定义（'环境'，'开发'）；/*

• 错误报告

  if (defined('ENVIRONMENT')) { switch (ENVIRONMENT) { case 'development': // 报告所有错误 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.');
  }
  

  }

I am not sure what was the real reason but I had a PHP installation with left-over php.ini file. Later I installed the full WAMP stack with its own PHP. When I deleted the leftover php.ini file from the previous installation then it started working as it should. It seems the PHP binaries in the new installing was using using the left-over php.ini which was in totally different directory; maybe because that directory was in environment PATH.

我不确定真正的原因是什么，但我有一个带有剩余 php.ini 文件的 PHP 安装。后来我用自己的 PHP 安装了完整的 WAMP 堆栈。当我从以前的安装中删除剩余的 php.ini 文件时，它开始正常工作。新安装中的 PHP 二进制文件似乎使用的是完全不同目录中的剩余 php.ini；也许是因为该目录在环境 PATH 中。
