问题：
我继承了一个用 PHP 调用 C# windows 服务的软件。它不能正常工作，所以我刚刚开始使用 WCF 和 SOAP。
我的主要问题是我无法使用 PHP 和 Soap 调用 Windows 服务。当我尝试它时，PHP 崩溃了。
我完成了 microsoft 教程： https ://docs.microsoft.com/en-us/dotnet/framework/wcf/getting-started-tutorial 当我使用教程中描述的 C# 客户端时，一切都像魅力一样工作。我添加了一个安装程序以使整个程序可作为 Windows 服务使用。长话短说，在 C# 中，一切都按预期工作。
我假设它只是没有为 SOAP 调用正确配置。我已经通读了：http ://www.rizalalmashoor.com/blog/calling-a-wcf-service-from-php/但我仍然无法让它运行。
问题：
源代码在下面。我想先提出我的问题：
1）我在基地址公开服务，对吗？
http://localhost:1234/GettingStartedLib/CalculatorService
2) http 端点为空。PHP 代码中的soapURL 是否正确？
3）有没有办法调试soap调用？即使我在 ZendStudio 中将它作为 CLI 应用程序进行调试，我也没有得到任何进一步的信息。
如果需要或没有得到充分解释，我很乐意提供更多信息。
- 在有人回答之前：在 php.ini 中启用了 Soap。已经检查过了。
源代码：
PHP：
$soapURL = 'http://localhost:1234/GettingStartedLib/CalculatorService?wsdl';
$soapAttributes = array('soap_version' => SOAP_1_1);
$result = new SoapClient($soapURL, $soapAttributes);
WCF库的配置：

<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true"/>
