首先大家要简单了解了何谓webservice，接下来就做两个非常简单的例子，webservice还是逃不开server端与client端。

我测试的环境为：apache2.2.11 php5.2.10

做这个测试之前，要确认你的php配置文件中已经将soap扩展打开，即extension=php_soap.dll;
OK 现在我们来体验webservice 

//server端 serverSoap.php 

$soap = new SoapServer( null , array( 'uri' => "http://192.168.1.179/")); //This uri is your SERVER ip. 
$soap -> addFunction( 'minus_func');                                                                                                //Register the function 
$soap -> addFunction( SOAP_FUNCTIONS_ALL); 
$soap -> handle(); 

function minus_func( $i , $j ){ 
      $res = $i - $j; 
      return $res; 
} 

//client端 clientSoap.php 
try { 
      $client = new SoapClient( null , 
              array( 'location' => "http://192.168.1.179/test/serverSoap.php" , 'uri' => "http://127.0.0.1/") 
      ); 
      echo $client -> minus_func( 100 , 99); 

} catch ( SoapFault $fault ){ 
      echo "Error: " , $fault -> faultcode , ", string: " , $fault -> faultstring; 
}


这是客户端调用服务器端函数的例子，我们再搞个class的。 

//server端 serverSoap.php 
$classExample = array(); 

$soap = new SoapServer( null , array( 'uri' => "http://192.168.1.179/" , 'classExample' => $classExample)); 
$soap -> setClass( 'chesterClass'); 
$soap -> handle(); 

class chesterClass { 
      public $name = 'Chester'; 

      function getName() { 
              return $this -> name; 
      } 
} 

//client端 clientSoap.php 

try { 
      $client = new SoapClient( null , 
              array( 'location' => "http://192.168.1.179/test/serverSoap.php" , 'uri' => "http://127.0.0.1/") 
      ); 
      echo $client -> getName(); 

} catch ( SoapFault $fault ){ 
      echo "Error: " , $fault -> faultcode , ", string: " , $fault -> faultstring; 
}



以上代码我已经测试通过。
