Sending WSDL file via SOAP

you must load nusoap library

Ok, its working well now. but i have the example of this library.
that means will give me "Fruits   apple 4".

I have to read a DB or whatever and then send it by WSDL to a Client. im stuck in this!
Im going to write whole my code in controller & ... except the NuSoap library (because its same).

HOW can i get the data(source isnt important right now) ,  convert to WSDL and then response to the Client?

My Controller

PHP Code:

class NuSoapServer extends CI_Controller {
function __construct()
    {
        parent::__construct();
        $ns = base_url();
        $this->load->library("Nusoap_library");
        $this->load->library("Master"); 
        $this->server = new soap_server(); // it is a soap server object
        $this->server->configureWSDL("SOAP", $ns); // configure wsdl
        $this->server->wsdl->schemaTargetNamespace = $ns; // namespace for the server
    }


    function index()
    {
        $ns = base_url();
        $input_array = array ('count' => 'xsd:integer', 'type' => "xsd:string"); // method parameters
        $return_array = array ("fruit" => "xsd:string");
        
        //soapAction
        $this->server->register(
            'Master.fruits', 
            $input_array, 
            $return_array, 
            "urn:SOAPServerWSDL", 
            "urn:".$ns."/fruits", 
            "rpc", 
            "encoded", 
            "Fruit Types"
        );
        
        $this->server->service(file_get_contents("php://input")); // reading raw data 
    }

    function client(){
        $this->client = new nusoap_client(base_url()."/index.php/interface/nusoapserver?wsdl", true);

        $this->load->view("client");
    }
} 


My master.php in libraries folder

PHP Code:

class Master {
 public function fruits($count, $type)
 {
   switch($type)
   {
    case 'red':
     return $count." Apple";
     break;
    case 'yellow':
      return $count." banana";
      break;
    }
  } 


My Client.php in view folder

PHP Code:

<?php

$error = $this->client->getError();
if ($error) 
{
 echo "<h2>Constructor error</h2><pre>" . $error . "</pre>";
}
 
  $result = $this->client->call("Master.myfile", array("count" => 4, "type" => "red"));
 
 if ($this->client->fault) 
{
   echo "<h2>Fault</h2><pre>";
   print_r($result);
   echo "</pre>";
   }
  else {
    $error = $this->client->getError();
   if ($error) {
    echo "<h2>Error</h2><pre>" . $error . "</pre>";
       }
  else {
    echo "<h2>Correct result</h2><pre>";
    echo $result;
    echo "</pre>";
   }
}
