我遇到了一个问题，当我使用 Try Catch block 时，我的 PHP 项目没有捕获异常。当抛出异常时，PHP 仍会显示异常的错误消息并结束 PHP 脚本的执行。我已将其范围缩小到我构建了一个自定义 PHP 错误处理程序这一事实。一旦我删除了我的自定义 PHP 处理程序，TRY CATCH block 就会再次正常工作。不幸的是，删除自定义错误处理程序不是一种选择。请看下面的代码:

我还包含了一个未捕获代码的 catch block 示例:
try {
$response = $client->GetAllOrdersByOrderNo($request);
} catch (Exception $e) {
$response = null;
}
类调用异常
<?php
namespace Base\Members\Library;
use \SoapClient;
use \SimpleXMLElement;
class MembershipAPI
{
public static function getOrderByOrderNo($orderNo) {
$client = new SoapClient("https://bah.foo.com/members/Services/Orders.svc?wsdl");
$request = array(array());
$request['request']['OrderNo'] = $orderNo;
try {
$response = $client->GetAllOrdersByOrderNo($request);
} catch (Exception $e) {
// This code is never set
$response = null;
}
/*if (response.OperationStatus != Orders.ExternalServiceResponseStatus.Success)
{
throw new Exception(response.OperationErrors[0]);
} */
return isset($response->GetAllOrdersByOrderNoResult->Orders->Order) ? $response->GetAllOrdersByOrderNoResult->Orders->Order : null;
}
}
最佳答案
try {
$response = $client->GetAllOrdersByOrderNo($request);
} catch (Exception $e) {
// This code is never set
$response = null;
}
您位于命名空间 Base\Members\Library 中。
该 block 正在捕获 Base\Members\Library\Exception
尝试在全局命名空间中捕获\Exception。
