Php5 Soap - Passing arrays via WSDL

I have a wsdl file which describes a service written in php5 - currently the resultant array provided by the soap server to a php5 soap client winds up as a empty stdClass rather than an array. I have written a class (with one method only) which is supposed to return a simple array.

Flash sees the web service and appears to validate it, however as its expecting an array no data results from the call using web services in flash either.

When testing the class on the server the class returns an array correctly so I know the function works.

What I need to establish is if the wsdl file is correctly describing the service, the wsdl was generated by a creator class (www.jool.nl/webservicehelper/).

I show the code below along with the wsdl file.

CODE (server)
<?php
//require the various classes that we use
require_once '../conn/conn.php';  

require_once('../classes/JewelleryService.class.php');
//set up the caching for wsdl
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache]    

    $server = new SoapServer("http://www.datafodder.net/wshelper15/service.php?class=JewelleryService&wsdl");
    $server->setClass("JewelleryService");
    $server->handle();    
?>

CODE FOR CLASS
<?php
require_once '../conn/conn.php';
require_once("../classes/db/MySQLConnect.php");

/**
  *
  * This webservice provides access to the Jewellery range data
  * and allows searching and other functions
  */
     
  class JewelleryService {

/**                            
  *                          
  * @return void
  */                      
      function __construct() {
      //public function to set up class
      $this->db = MySQLConnect::getInstance(HOST,USERNAME,PASSWORD);
      }
       
/**                            
  *                          
  * This method returns a single product inside an array.
  * @param string product_id
  * @return product[]
  */
     
      public function getSingleProduct($product_id) {
        if ($product_id != "") {          
            $query = sprintf("SELECT * FROM products_prd WHERE sku_prd = '%s'",$product_id);            
            $data = $this->db->createResultSet($query, DATABASE);
           
            //pull the data from the db      
            foreach($data as $row ){
               
                $prods = array();
                $prods['product_id'] = $row['id_prd'];
                $prods['name'] = $row['name_prd'];
                $prods['price'] = $row['price_prd'];
                $prods['stocklevel'] = $row['stocklevel_prd'];
                $prods['description'] = $row['description_prd'];
                $prods['category'] = $row['category_prd'];
                $prods['rsize'] = $row['ring_size'];
            }                            
                return $prods;
        } else {
            throw new SoapFault("Server","No Request Made '$product_id'.");
        }
      }
     
     
    }
   
?>

CODE FOR CLIENT
<<Part shown that does the work>>
$client = new SoapClient("http://www.datafodder.net/wshelper15/service.php?class=JewelleryService&wsdl");

      try {
        $item = htmlspecialchars($_POST['sku']);
        $data = $client->getSingleProduct($item);
        //foreach($client->getSingleProduct($item) as $key => $value){
        var_dump($data);
        echo($data->name);
        //($key." = ".$value."<br>"); this was supposed to echo an array
        //}
               
      } catch (SoapFault $exception) {
        echo $exception;  
      }
