将请求发送到wsdl文件并使用php获取响应

我搜索了很多这部分，但我发现了很多问题，所以我混淆了它们

这是wsdl文件

$wsdl=http://url.com/service.wsdl';

下面是SOAP的定义。如何使用php文件发送请求并获得响应

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:ent="http://enterprise.olp.sadad.com/Infrastructure/EnterpriseContext" xmlns:ns="http://olp.sadad.com/sadadpaymentmanagement/service/sadadpaymentmanager/intf/1">
