PHP&“未发现异常". [英] PHP "Exception not found"

问题描述

我有一个有趣的问题.试图理解为什么某个网站向浏览器返回http代码500时，我发现了消息

I have a somehow funny issue. While trying to understand why a certain website returns http code 500 to browser, I found the message

PHP Fatal error:  Class 'MZ\\MailChimpBundle\\Services\\Exception' not found in /var/www/website/vendor/bundles/MZ/MailChimpBundle/Services/MailChimp.php on line 41

在Apache日志中.看上面提到的那一行:

in apache log. Looking at the mentioned line:

throw new Exception('This bundle needs the cURL PHP extension.');

我现在了解了如何使站点正常工作，但是我仍然想知道引发异常的代码(会导致更有用的日志消息)为什么失败了.可能是什么原因?

I now understand how to get the site working, but I still wonder why the code for throwing the exception (which would have resulted in a more helpful log message) failed. What could be the reason?

推荐答案

MZMailChimpBundle 不包含在 MZ \ MailChimpBundle \ Services 名称空间中名为 Exception 的类.

The MZMailChimpBundle does not contain a class named Exception within the MZ\MailChimpBundle\Services namespace.

由于这个简单的事实，并且由于异常应该发出的错误消息与集成问题(检查curl库)有关，因此我认为这是一个错误.

Because of that simple fact and as the error message that the exception should signal is related to an integration problem (check for the curl library) I assume that this is a bug.

原文是 \ Exception 的意思，而不是 Exception 的意思.这是名称空间可能会发生的一个常见错误.要修复文件，请别名/将 \ Exception 导入为 Exception :

The original has meant \Exception and not Exception here. It's a somewhat common mistake that can happen with namespaces. To fix the file, either alias/import \Exception as Exception:

namespace MZ\MailChimpBundle\Services;
use Exception;

和/或更改new 行"rel =" noreferrer"> MZMailChimpBundle/Services/MailChimp.php :

and/or change the new line in MZMailChimpBundle/Services/MailChimp.php:

throw new \Exception('This bundle needs the cURL PHP extension.');

还请参见相关问题:如何使用php的根"命名空间?以及具有相同名称的那个找不到类'Namespace \ Example'错误消息:从PHP中另一个命名空间中的类调用静态方法.
