Fatal error: Class 'Response' not found - php

Question

I'm working with Abraham's twitteroauth to implement Twitter OAuth in my application. While running my application, this is the error I'm encountering:
Fatal error: Class 'Response' not found in /opt/lampp/htdocs/tmhOAuth-master/twitteroauth.php on line 108
Now, this is what my twitteroauth.php file looks like till the 108th line:
<?php
/**
* The most popular PHP library for use with the Twitter OAuth REST API.
*
* #license MIT
*/
//namespace twitteroauthm\src\TwitterOAuth;
//use twitteroauthm\src\TwitterOAuth;

require "twitteroauthm/autoload.php";
use Abraham\TwitterOAuth\TwitterOAuth as Config;
//require_once("twitteroauthm/src/TwitterOAuth.php");
//use twitteroauthm\src\TwitterOAuth;
//require_once("twitteroauthm/src/Config.php");
/**

*/
class TwitterOAuth extends Config
{
const API_VERSION = '1.1';
const API_HOST = 'https://api.twitter.com';
const UPLOAD_HOST = 'https://upload.twitter.com';

public function __construct($consumerKey, $consumerSecret, $oauthToken = null, $oauthTokenSecret = null)
{
$this->resetLastResponse();
$this->signatureMethod = new HmacSha1();
$this->consumer = new Consumer($consumerKey, $consumerSecret);
if (!empty($oauthToken) && !empty($oauthTokenSecret)) {
$this->token = new Token($oauthToken, $oauthTokenSecret);
}
if (empty($oauthToken) && !empty($oauthTokenSecret)) {
$this->bearer = $oauthTokenSecret;
}
}
/**
* #param string $oauthToken
* #param string $oauthTokenSecret
*/
public function setOauthToken($oauthToken, $oauthTokenSecret)
{
$this->token = new Token($oauthToken, $oauthTokenSecret);
}
/**
* #return string|null
*/
public function getLastApiPath()
{
return $this->response->getApiPath();
}
/**
* #return int
*/
public function getLastHttpCode()
{
return $this->response->getHttpCode();
}
/**
* #return array
*/
public function getLastXHeaders()
{
return $this->response->getXHeaders();
}
/**
* #return array|object|null
*/
public function getLastBody()
{
return $this->response->getBody();
}
/**
* Resets the last response cache.
*/
public function resetLastResponse()
{
$this->response = new Response();
}
What seems to be wrong with my code? Is there a way to include the Response class into my file that I'm not aware of?
I'm also including a few screenshots to give an overview of my project's file structure:

Answer 1

as you are using namespaces, add 'use Response' at the top, as for now your response class is not recognized
same way as you are using Confing, just make sure linke to Response class will be recognized.
use Abraham\TwitterOAuth\TwitterOAuth as Config;
use Abraham\TwitterOAuth\Response as Response;
or try to include it at the top:
require_once('your_path/Response.php');
