Lost parameter calling WS from PHP

Question

Hi,

I'm trying to call this WS from PHP:

namespace WsInteropTest
{
    /// <summary>
    /// Summary description for Service1
    /// </summary>
    [WebService(Namespace = "http://advantage-security.com/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class TestWs : System.Web.Services.WebService
    {
        [WebMethod]
        public string HelloWorld(int entero)
        {
            return "Hello World " + entero.ToString();
        }
    }
}

The code i use to call the WS is this:

<?php
        require_once('nusoap\nusoap.php');
  $client = new nusoap_client('http://localhost/testws/TestWS.asmx?WSDL');

  $params = array(
   'entero' => 100
  );

  $result = $client->call('HelloWorld', array($params), 
      'http://advantage-security.com/HelloWorld',
      'http://advantage-security.com/HelloWorld');
  print_r($result);
  ?>

and the result is this

Hello World 0

What do you think may be the problem?

According to what i've read there is no issues with simple types between .NET (which are converted to standard soap types) and PHP.

If it is of use, here it is the WSDL.

Thanks in advance

Answer 1

Shouldn't it be (since $params is already an array)

//you're passing array($params)
$result = $client->call('HelloWorld', $params, 
    'http://advantage-security.com/HelloWorld',
    'http://advantage-security.com/HelloWorld');

Answer 2

I couldn't find out what was happening here, so i decided to use instead the Soap librery built into Php 5.2.

The solution was this:

$client = new SoapClient("http://localhost/testws/TestWS.asmx?WSDL");
        $params = array(
            'entero' => 77
        );
        $result = $client->HelloWorld($params);
        print_r($result->HelloWorldResult);
