PHP捕获未使用自定义异常处理程序捕获异常
我遇到了一个问题，当我使用Try-Catch块时，我的PHP项目没有捕获异常。当抛出异常时，PHP仍将显示异常的错误消息，并将结束PHP脚本的执行。我已经把范围缩小到我有一个定制的PHP错误处理程序。一旦我删除了我的定制PHP处理程序，然后尝试CATCH块再次正常工作。不幸的是，删除自定义错误处理程序不是一个选项。请参见下面的代码：PHP捕获未使用自定义异常处理程序捕获异常,php,exception,error-handling,try-catch,custom-error-handling,Php,Exception,Error Handling,Try Catch,Custom Error Handling,我遇到了一个问题，当我使用Try-Catch块时，我的PHP项目没有捕获异常。当抛出异常时，PHP仍将显示异常的错误消息，并将结束PHP脚本的执行。我已经把范围缩小到我有一个定制的PHP错误处理程序。一旦我删除了我的定制PHP处理程序，然后尝试CATCH块再次正常工作。不幸的是，删除自定义错误处理程序不是一个选项。请参见下面的代码： use \ErrorException; use \BrowserDetection; use \DateTime; use \D

请尝试在全局命名空间中捕获\Exception。引发新异常的
GetAllOrdersByOrderNo引发新异常（“某些错误”）\Exception\Exception带有catch（\expetion$e）
。我已对其进行了编辑并将其添加到中供您查看。但是，即使在此代码之外，也无法捕获任何异常，即使它位于全局命名空间中。您不会从SoapClient类RPC调用中获取PHP异常，因为SoapClient没有异常，例如$client->GetAllOrdersByOrderNo（$request）
永远不会抛出异常，即使远程系统抛出异常，如果它应该将异常或错误输出给您，那么您必须解析结果以检查它是否处于错误状态。还要注意的是，PHP编程错误不是PHP中的例外，它们是错误，您能否提供失败状态响应的演示echo”“.print_r（$response，true）。”我可以，但我认为你对SoapClient类的关注太多了。这只是一个例子，任何抛出异常的类都不能被try-catch捕获。所以，如果我只是抛出一个新的异常（“Hello World”），它仍然不会被捕获。这就解决了问题。谢谢
