PHP“未找到异常”； [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。
看上面提到的行：

in apache log. Looking at the mentioned line:

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

我现在了解如何使网站正常运行，但我仍然想知道为什么抛出异常的代码（这将导致更有用的日志消息）失败。
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 在 MZ\MailChimpBundle\Services <中不包含名为 Exception 的类。 / code>名称空间。

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

由于这个简单的事实以及错误消息（该异常应该发出信号）与集成问题有关（请检查curl库）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.

原始含义是 \Exception 而不是例外在这里。命名空间可能会发生一些常见的错误。要修复文件，请别名/导入 \Exception 作为 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 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？，并且找不到具有相同 Class'Namespace\Example'的错误消息：从PHP另一个命名空间中的类调用静态方法。
