白屏死亡！ [英] White screen of death!

问题描述

调试安装在新开发环境中的代码标识符应用程序后，当看到没有更多可用的白屏时，我已经开始惊奇了。我已经能够解决造成这种情况的每一个错误，但是它已经采取了严重的时间太长。

PHP error_reporting（E_ALL）& display_errors，1 也被设置，我甚至安装Xdebug希望获得更多的输出，但不是。我的日志记录设置也正常，但没有写入日志

有没有办法得到一些信息，而不是一个完整的白色屏幕？这肯定会缩短我花费在解决导致这种情况的最终错误的时间？ / p>

非常感谢！

为什么代码点火器给我一个白页？

解决方案

我发现，自从我的问题的时候，似乎没有确保错误总是输出与PHP，这似乎在这里和那里抛出白色的屏幕。

我发现最好的解决方法是使用以下行来确保将错误记录放入一个文件e应用程序易于访问和监视：

  ini_set（'error_log'，MYPATH。'logs / errorlog.log'）; 
  

据我测试过，当出现白屏时，它也会被登录到这个错误日志。似乎是最简单的方式来知道发生什么事情会发生什么。

After debugging a codeigniter app that were installed into a new development environment, I have started to freak out when seeing white screens with nothing more available. I have been able to solve each and every one of the errors that have caused this, but it have taken seriously way too long time.

PHP error_reporting(E_ALL) & display_errors", 1 is set as well. I even installed Xdebug in hope of getting more output, but no. My logging settings are also working, but nothing is written to the log.

Is there a way to get something informative printed out instead of a complete white screen? It would certainly shorten my time spent on solving the eventual errors that causes this?

Thanks a lot!

解决方案

I've found out, since the time of my question, that nothing seems to ensure that errors are always outputted with PHP, which seems to throw white screens here and there. Regardless of PHP's ini-settings.

I've found out that the best workaround however is to use the following line to ensure that error logging is put into a file easily accessed and monitoredby the application:

ini_set('error_log', MYPATH .'logs/errorlog.log'); 

As far as I've tested it, when white screens appear - it also gets logged into this errorlog. Seems to be the easiest way to know what happens when things go wrong.
