如何创建PHP SOAP客户端并将结果xml存储在php变量中

我需要构建一个Soap PHP客户端,它从一个调用和检索信息
?Soap服务器.NET Web服务.

我目前正致力于为荷兰医疗保健系统的医生提供信息
.对于在荷兰医疗保健系统注册的每位医生,您都可以检索
他的信息来自使用WSDL的SOAP Web服务的唯一唯一BIG ID(11位唯一编号).

所以当我调用SOAP服务器时：
(服务器链接如下)

进入这个测试网站(如soapclinet.com)

我的XML响应是正确的,看起来与下面的XML完全相同
括号中我想要在php中捕获的医生的信息.

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
 <ListHcpApprox3Result xmlns="http://services.cibg.nl/ExternalUser">
  <ListHcpApprox>
   <ListHcpApprox3>
    <HcpNumber>200822</HcpNumber>
    <BirthSurname> [Surname of the Doctor]</BirthSurname>
    <MailingName> [Mailing name of the doctor] </MailingName>
    <Initial> [Initials of the doctor] </Initial>
    <Gender> [Gender of the doctor] </Gender>
    <ArticleRegistration>
    <ArticleRegistrationExtApp>
    <ArticleRegistrationNumber> [unique BIG ID]  </ArticleRegistrationNumber>
    <StartDate>1998-12-10T00:00:00</StartDate>
    <EndDate xsi:nil="true"/>
    <TypeOfSpecialismId>15</TypeOfSpecialismId>
    </SpecialismExtApp>
    </Specialism>
    <Mention/>
    <JudgmentProvision/>
    <Limitation/>
   </ListHcpApprox3>
  </ListHcpApprox>
 </ListHcpApprox3Result>
</soap:Body>
</soap:Envelope>

我需要构建一个PHP网页,它将执行完全相同的SOAP调用.

wsdl文件的地址是这样的：

webservices.cibg.nl/Ribiz/OpenbaarV2.asmx?wsdl.asmx?wsdl

soap服务器地址是这样的：
http://webservices-acc.cibg.nl/Ribiz/OpenbaarV2.asmx

肥皂行动是这样的：
http://services.cibg.nl/ExternalUser/ListHcpApprox3

我发送的SOAP消息是这样的：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
 <listHcpApproxRequest xmlns="http://services.cibg.nl/ExternalUser">
  <WebSite>Ribiz</WebSite>
  <RegistrationNumber> [BIG ID number of the doctor] </RegistrationNumber>
 </listHcpApproxRequest>
</soap:Body>
</soap:Envelope>

(括号内是我们在SOAP服务器中发送的医生的BIG ID号)

如何将上述SOAP操作编写到PHP代码中并在PHP中存储我作为响应获取的XML变量？

我需要在php代码中存储的XML响应中的变量是这些……

<HcpNumber>200822</HcpNumber>
<BirthSurname> [Surname of the Doctor]</BirthSurname>
<MailingName> [Mailing name of the doctor] </MailingName>
<Initial> [Initials of the doctor] </Initial>
<Gender> [Gender of the doctor] </Gender>

Update1：??这是var_dump的输出.其中xxxxxxx是我想要存储在php变量中的值！

object(stdClass)[2]
  public 'ListHcpApprox' => 
    object(stdClass)[3]
      public 'ListHcpApprox3' => 
        object(stdClass)[4]
          public 'HcpNumber' => string 'xxxxxxxxx' (length=6)
          public 'BirthSurname' => string 'xxxxxxxxxxx' (length=9)
          public 'MailingName' => string 'xxxxxxxxxxxxxxxxxx' (length=18)
          public 'Initial' => string 'xxxxxxxxxxxx' (length=8)
          public 'Gender' => string 'x' (length=1)
          public 'ArticleRegistration' => 
            object(stdClass)[5]
              ...
          public 'Specialism' => 
            object(stdClass)[7]
              ...
          public 'Mention' => 
            object(stdClass)[9]
              ...
          public 'JudgmentProvision' => 
            object(stdClass)[10]
              ...
          public 'Limitation' => 
            object(stdClass)[11]
              ...
