php解析wsdl入门级经典教程

国内用PHP写WebService的真的很少，网上资料也没多少，公司的项目开发过程中，经历了不少这方面的东西，写出来以供大家参考（谢谢老农提供的WSDL和程序文件）

客户端

<?php
header ( "Content-Type: text/html; charset=utf-8" );

$ws = "http://soap/soapCspMessage.php?wsdl";
$client = new SoapClient ( $ws, array ('trace' => 1,'uri' => 'http://www.zxsv.com/SoapDiscovery/' ));

echo ("SOAP服务器提供的开放函数:");
echo ('<pre>');
var_dump ( $client->__getFunctions () );
echo ('</pre>');
echo ("SOAP服务器提供的Type:");
echo ('<pre>');
var_dump ( $client->__getTypes () );
echo ('</pre>');
echo ("执行GetGUIDNode的结果:");
//$users = $client->GetUsers();
//var_dump($HelloWorld );
$parameters =array('uname'=>'zxsv',"upassword"=>'123');
    $out =$client->HelloWorld($parameters);
    $datadb =$out->HelloWorldResponse;
   var_dump($out);
?>

服务端

<?php
class Member
{
    public$UserId;
    public$Name;
    publicfunction __construct($parmas){
       $this->UserId = $parmas[0];
       $this->Name = $parmas[1];
    }
}
$servidorSoap = new SoapServer('testphp.xml',array('uri'=>'http://www.TestPHP.com/','encoding'=>'utf-8','soap_version'=> SOAP_1_2 ));
$servidorSoap->setClass(Testphp);
$servidorSoap->handle();
class Testphp {
    publicfunction HelloWorld($uid){
       returnarray('HelloWorldResult'=>"mystring".$uid->{'uname'}.'and '.$uid->{'upassword'});
    }
    publicfunction GetMember($uid){
       $s=array();
       for($i=0;$i<$uid->{'uid'};$i++){
           $s[] =&new Member(array($i,$uid->{'uname'}.'我测试'.$i)); 
       }
       return  array('GetMemberResult'=>$s);
    }
}
?>

到这里应该都看的懂吧
下面是WSDL文件

这里有返回的两个字段，一个是返回字符串，这个很好理解

<s:elementname="HelloWorld">
       <s:complexType>
         <s:sequence>
           <s:element minOccurs="0" maxOccurs="1" name="uname"type="s:string" />
           <s:element minOccurs="0" maxOccurs="1"name="upassword" type="s:string" />
         </s:sequence>
       </s:complexType>
     </s:element>
     <s:elementname="HelloWorldResponse">
       <s:complexType>
         <s:sequence>
           <s:element minOccurs="0" maxOccurs="1"name="HelloWorldResult" type="s:string" />
         </s:sequence>
       </s:complexType>
     </s:element>

这一段就字符串的
那返回数组的就比较麻烦了，我和老农搞了一两周才发现是WSDL文件写错了，看下面的一段

     <s:element name="GetMember">
       <s:complexType>
         <s:sequence>
           <s:element minOccurs="1" maxOccurs="1" name="uid"type="s:int" />
           <s:element minOccurs="0" maxOccurs="1" name="uname"type="s:string" />
         </s:sequence>
       </s:complexType>
     </s:element>
     <s:elementname="GetMemberResponse">
       <s:complexType>
         <s:sequence>
           <s:element minOccurs="0" maxOccurs="1"name="GetMemberResult" type="tns:ArrayOfMember"/>
         </s:sequence>
       </s:complexType>
     </s:element>
     <s:complexTypename="ArrayOfMember">
       <s:sequence>
         <s:element minOccurs="0" maxOccurs="unbounded"name="Member" nillable="true" type="tns:Member"/>
       </s:sequence>
     </s:complexType>
     <s:complexType name="Member">
       <s:sequence>
         <s:element minOccurs="1" maxOccurs="1" name="UserId"type="s:int" />
         <s:element minOccurs="0" maxOccurs="1" name="Name"type="s:string" />
       </s:sequence>
     </s:complexType>

第一段GetMember是输入，最重要的是GetMemberResponse这段，看type="tns:ArrayOfMember"这里，返回一个数组，WSDL中定义了ArrayOf这个，后面的就简单了，ArrayOfMember的类型是type="tns:Member"，从name="Member"得到要返回的数组，完工。
