本文实例讲述了PHP中soap的用法，分享给大家供大家参考。具体用法分析如下：

PHP 使用soap有两种方式。

一、用wsdl文件

服务器端：

复制代码 代码如下:<?php

class service

{

public function HelloWorld()

{

return "Hello";

}

public function Add($a,$b)

{

return $a+$b;

}

}

$server=new SoapServer('soap.wsdl',array('soap_version' => SOAP_1_2));

$server->setClass("service");

$server->handle();

?>

资源描述文件，可以用工具(zend studio)生成。其实就是一个xml文件。

复制代码 代码如下:<"1.0" encoding="UTF-8"?>

<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://localhost/interface/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="soap" targetNamespace="http://localhost/interface/">

<wsdl:types>

<xsd:schema targetNamespace="http://localhost/interface/">

<xsd:element name="HelloWorld">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="in" type="xsd:string"/>

</xsd:sequence>

</xsd:complexType>

</xsd:element>

<xsd:element name="HelloWorldResponse">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="out" type="xsd:string"/>

</xsd:sequence>

</xsd:complexType>

</xsd:element>

<xsd:element name="Add">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="in" type="xsd:int"></xsd:element>

</xsd:sequence>

</xsd:complexType>

</xsd:element>

<xsd:element name="AddResponse">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="out" type="xsd:int"></xsd:element>

</xsd:sequence>

</xsd:complexType>

</xsd:element>

</xsd:schema>

</wsdl:types>

<wsdl:message name="AddRequest"> <wsdl:part name="a" type="xsd:int"></wsdl:part>

<wsdl:part name="b" type="xsd:int"></wsdl:part>

</wsdl:message>

<wsdl:message name="AddResponse">

<wsdl:part name="c" type="xsd:int"></wsdl:part>

</wsdl:message>

<wsdl:portType name="TestSoap"> <wsdl:operation name="Add">

<wsdl:input message="tns:AddRequest"></wsdl:input>

<wsdl:output message="tns:AddResponse"></wsdl:output>

</wsdl:operation>

</wsdl:portType>

<wsdl:binding name="soapSOAP" type="tns:TestSoap">

<soap:binding

transport="http://schemas.xmlsoap.org/soap/http" />

<wsdl:operation name="Add">

<soap:operation soapAction="http://localhost/interface/Add" />

<wsdl:input>

<soap:body use="literal"

namespace="http://localhost/interface/" />

</wsdl:input>

<wsdl:output>

<soap:body use="literal"

namespace="http://localhost/interface/" />

</wsdl:output>

</wsdl:operation>

</wsdl:binding>

<wsdl:service name="TestSoap">

<wsdl:port binding="tns:soapSOAP" name="soapSOAP">

<soap:address location="http://localhost/interface/myservice.php"/>

</wsdl:port>

</wsdl:service>

</wsdl:definitions>

客户端调用：

复制代码 代码如下:<?php

$soap = new SoapClient('http://localhost/interface/soap.wsdl');

echo $soap->Add(1,2);

?>

二、不用wsdl文件

服务器端：

复制代码 代码如下:<?php

class service

{

public function HelloWorld()

{

return "Hello";

}

public function Add($a,$b)

{

return $a+$b;

}

}

$server=new SoapServer(null,array('uri' => "abcd"));

$server->setClass("service");

$server->handle();

?>

客户端：

复制代码 代码如下:<?php

try{

$soap = new SoapClient(null,array(

"location" => "http://localhost/interface/soap.php",

"uri" => "abcd", //资源描述符服务器和客户端必须对应

"style" => SOAP_RPC,

"use" => SOAP_ENCODED

));

echo $soap->Add(1,2);

}catch(Exction $e){

echo print_r($e->getMessage(),true);

}

?>
