php soap扩展开启与__soapCall使用问题

例子

try {

      $client = new SoapClient("http://localhost:8080/Webtest/NewService?wsdl");

//    $result = $client->__soapCall("operation",array(4));//fault

//    $result = $client->__soapCall("operation",array("id"=>4));//fault

//    $result = $client->operation(4);//fault

    $result = $client->operation(array("id"=>4));//OK

    $back = json_encode($result);

    echo $back;

} catch (SoapFault $fault){

    echo "Error: ",$fault->faultcode,", string: ",$fault->faultstring;

}
?>
//仅有标记为OK的那行可以成功返回数字4，其它返回的都是数字0（参数应该是没有传过去，服务器端id初始是0）。

//手册里soapcall的例子：

$client = new SoapClient("some.wsdl");

$client->SomeFunction($a, $b, $c);

$client->__soapCall("SomeFunction", array($a, $b, $c));

$client->__soapCall("SomeFunction", array($a, $b, $c), NULL,

new SoapHeader(), $output_headers);

$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'));

?>
