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：
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。
<?xml version="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 style="document"
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：
$soap = new SoapClient('http://localhost/interface/soap.wsdl');
echo $soap->Add(1,2);
?>
二、不用wsdl文件
服务器端：
class service
{
public function HelloWorld()
{
return "Hello";
}
public function Add($a,$b)
{
return $a+$b;
}
}
$server=new SoapServer(null,array('uri' => "abcd"));
$server->setClass("service");
$server->handle();
?>
客户端：
<?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);
}
?>
希望本文所述对大家的PHP程序设计有所帮助。
