請教一下php調用java webservice的問題,不知道我的參數那裏錯呢?
結果總是出現:The named parameter value is not in the call parameters.
我的php 代碼如下

<?php   
require_once('SOAP/Client.php');   
$client = new SOAP_Client('http://localhost:8080/axis2/services/HelloWorldService?wsdl');   
  
$params = array('echoRequest'=>'World');   
$return = $client->call('echo',$params);   
echo $return;   
?>  

使用工具查看這支webservice的WSDL如下：

自己研究出來了
原來是要抓這一行的name
<s:element minOccurs="0" name="value" nillable="true" type="s:string" /> 

謝謝各位
