Getting PHP warnings in SOAP response along with success response in PHP - php

Question

When I am testing my SOAP sever, I am getting the PHP warning html message with success response.
The SOAP server is like below:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
ini_set("allow_url_fopen", "On");
$server = new SoapServer("../billerwebservice/BillerWS.wsdl"); // WSDL file for function definitions
$server->setClass("Payment");
//$server->addFunction(array("payAccount","confirmRequest","voidRequest")); // Same func name as in our WSDL XML, and below
$server->handle();
class payAccountResponse {
public $return;
}
class confirmResponse {
public $return;
}
class voidResponse {
public $return;
}
class Payment extends CI_Controller {
/*function __construct(){

Please let me know why I am getting these warnings.
