$client = new SoapClient(null, array('location' => "http://localhost/soap.php",
                                     'uri'      => "http://test-uri/"));
$client->SomeFunction($a, $b, $c);
$client->__soapCall("SomeFunction", array($a, $b, $c));
$client->__soapCall("SomeFunction", array($a, $b, $c),
                    array('soapaction' => 'some_action',
                          'uri'        => 'some_uri'));
?> 
 

1.in WSDL mode,soapCall应用web service,例子用的是asp.net的web service，提供service.asmx页面,调用及查看都比较简单,手册上的example也大多是这个类型，比较简单

SOAP发送的协议：

POST /servicepath/service.asmx HTTP/1.1
Host: 211.186.1.4
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://211.186.5.15/Service/ServiceMethod"

<?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>
    <ServiceMethod xmlns="http://211.186.5.15/Service">
      <param1>string</param1>
      <param2>string</param2>
      <param3>string</param3>
    </ServiceMethod>
  </soap:Body>
</soap:Envelope>

调用方法：
$client = new SoapClient("http://www.xxx.com/service/service.asmx?WSDL");
//向SOAP服务方发送参数值
$param1 = "p1";
$param2 = "p2";
$param3 = "p3";

//serviceParam1,serviceParam2,serviceParam3为发送参数值所对应的参数名（或service端提供的字段名）
$param = array('serviceParam1' => $param1,'serviceParam2' => $param2,'serviceParam3' => $param3);

//方法名为ServiceMethod,参数数组为$param，默认以parameters字段标示传递的参数数组
$arr = $client->__soapCall('ServiceMethod',array('parameters' => $param));
print_r($arr);

2.in non-WSDL mode,这种情况下soapaction is unknown

SOAP发送协议

POST /services/SoapMethod?WSDL HTTP/1.1
Host: 220.211.1.12:8088
Connection: Keep-Alive
User-Agent: PHP-SOAP/5.2.5
Content-Type: text/xml; charset=utf-8
SOAPAction: "urn:SoapMethod#ServiceMethod"
Content-Length: 1297

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:SoapMethod" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns2="http://220.211.1.12" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
<ns1:ServiceMethod>
<ServiceMethodSection xsi:type="ns2:ServiceObjectType">
<param1 xsi:type="xsd:string">01019</param1>
<param2 xsi:type="xsd:long">10</param2>
<param3 xsi:type="xsd:long">0</param3>
<param4 xsi:type="xsd:long">11</param4>
</ServiceMethodSection>
</ns1:ServiceMethod>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

调用方法：
2.1传递一个参数：
try {
      $client = new SoapClient(null,  
      array('location' => 'http://192.168.1.180:8088/services/SoapPage?WSDL','uri' => 'http://192.168.1.180:8088/services/'));   
      $result =  $client->__soapCall('ServiceMethod', array('fieldName' => "data")); //以数组形式传递params
      //$result =  $client->__soapCall('ServiceMethod', array(new SoapParam("data", 'fieldName')));  //以构造服务端参数的形式构造参数传递给服务端 
      var_dump($result);
  }
  catch (Exception $e)
  {
      printf("Message = %s",$e->__toString());
  }
  
附：手册解释
class SoapParam {

__construct ( mixed data, string name )

}
参数

data
The data to pass or return. You can pass this parameter directly as PHP value, but in this case it will be named as paramN and the SOAP Service may not understand it.

name
The parameter name

2.2传递多个参数：
如果服务端在non wsdl的情况下要求传递一个对象参数，该对象中包含多个属性,则code如下

try {
      $client = new SoapClient(null, array('location' => 'http://192.168.1.180:8088/services/SoapPage?WSDL','uri' => 'urn:SoapName'));   //uri部分也可能是uri地址

      class Obj{ 
       public $param1 = '01019';
       public $param2 = 10;
       public $param3 = 0;
       public $param4 = 11;
      }

    $struct = new Obj();  //创建服务端要求传递的对象
    //如果服务端变态到传递的参数有的参数类型是你编程语言中没有的数据类型，如本人用php,没有Java的Long类型(一般做web service都要考虑到通用性，数据类型都是string或int型，而且我认为根本没必要用Long类型。没办法服务端不改，只能我这边改)就要将参数进行强制类型转换处理，这样的处理也只是在SOAP传输中将xml的参数类型替换成服务端所要求的类型名，并不是真实转化传递的数据类型
    $struct->param1 = iconv('gb2312','utf-8',$struct->param1);
    $struct->param2 = new SoapVar($struct->param2,XSD_LONG);
    $struct->param3 = new SoapVar($struct->param3,XSD_LONG);
    $struct->param4 = new SoapVar($struct->param4,XSD_LONG);

    //序列化对象中使用SoapVar的方法参考php手册对SoapVar的解释，每个参数都解释的很清楚
    $soapstruct = new SoapVar($struct, SOAP_ENC_OBJECT, "ServiceObjectType", "http://soapinterop.org/xsd"); //对象序列化,注意区分，SOAP对象的序列化不是用serialize
    
      $result =  $client-> ServiceMethod(new SoapParam($soapstruct, 'ServiceMethodSection'));
     //$result =  $client->__soapCall('ServiceMethod', array(new SoapParam($soapstruct, 'ServiceMethodSection')));
    
      var_dump($result);
  } catch (Exception $e) {
      printf("Message = %s",$e->__toString());
  }

SoapVar
SoapVar -- Changes the Returntype of a variable
Description

new SoapVar (mixed variable, long type)

You can change the return type of variable - so that it works better with non-PHP applications for example.

type should be one of the following
