如何配置PHP显示详细的错误而不是错误500页？ [英] How to configure PHP to display detailed errors instead of error 500 page?

问题描述

我有一个PHP应用程序部署在我的IIS托管，我总是得到通用IIS错误500页面，而不是详细的错误页面。

我明白我需要修改一些php.ini文件（从这个问题）。

似乎display_errors设置正确：

  echo ini_get '的display_errors'）; 
  

输出 1 。

我还尝试在导致错误的函数中设置display_errors和error_reporting（我知道特定的功能是问题，因为我手动修改它）。

  function sendEmail（$ aForm，$ sFile ='messages.tpl'，$ sTargetEmail = null）{
 error_reporting（E_ALL）; 
 ini_set（'display_errors'，'On'）; 
 //其余的功能
  

编辑：我知道我应该将这些值设置为一些php.ini文件 - 当我只能通过FTP访问我的应用程序文件夹时，如何在共享主机上指定php.ini值？

如何识别错误详细信息？

解决方案

看起来像我这样打开'display_errors'，但您的托管服务提供商正在重定向您的500错误页面到不显示错误的自定义页面。不是一个很好的设置，但我会联系您的托管服务提供商，希望他们能够解释这个问题。有可能在IIS上的.user.ini文件见
见http://learn.iis.net/page.aspx/745/enable-per-site-php-configuration-on- iis-60-and-iis-7-and-above /
再次只有您的托管服务提供商才知道是否设置了这个。

I have a PHP application deployed on my IIS hosting and I am always getting generic IIS "error 500" pages insteady of detailed error pages.

I understand I need to modify some php.ini file (from this question).

It seems that display_errors is set correctly:

echo ini_get('display_errors');

outputs 1.

I have also tried setting display_errors and error_reporting in the function that causes the error (I know the particular function is the problem because I manually modified it).

function sendEmail( $aForm, $sFile = 'messages.tpl', $sTargetEmail = null ){ 
  error_reporting(E_ALL);
  ini_set('display_errors', 'On');
  //rest of the function

EDIT: I know I should have set these values in some php.ini file - how can I specify php.ini values on a shared hosting, when I have only access to my app folder via FTP?

How can I identify the error details?

解决方案

It looks to me like you do have 'display_errors' turned on but your hosting provider is redirecting your 500 error page to a custom page which doesn't display the errors. Not a great set up but I would contact your hosting provider in the hope that they can shed some light on the problem. It is possible to have .user.ini files on IIS see see http://learn.iis.net/page.aspx/745/enable-per-site-php-configuration-on-iis-60-and-iis-7-and-above/ again only your hosting provider would know if this is set up.
