How to get twitter's user Access Token?

Question

I am using https://twitteroauth.com/ in my some PHP pages. I want to get user access token and access secret token. I got my answer on this page: How to get user Access Token and Access Secret with the Twitter API using php

After replacing my consumer key and secret consumer key on both pages. I upload it on my server but then I got the following error when I open twitter-go.php

Fatal error: Uncaught exception `'Abraham\TwitterOAuth\TwitterOAuthException'` with message 

'<?xml version="1.0" encoding="UTF-8"?>
<hash> 
    <error>Desktop applications only support the oauth_callback value 'oob'</error>
    <request>/oauth/request_token</request>
</hash> '
in `/home/mediahyp/public_html/tweetme/twitteroauth/src/TwitterOAuth.php:138` 

Stack trace:

#1 {main} thrown in /home/mediahyp/public_html/tweetme/twitteroauth/src/TwitterOAuth.php on line 138

Can anyone tell me what is this error about? Am I missing something or something else.

The new interface simplifies this: if you provide a placeholder callback URL in the field for it in your application detail screen, it allows you to use dynamic callbacks. So just go ahead and put a placeholder in there (doesn't have to be the actual dynamic/runtime callback you use) and you'll be able to use other forms of auth.

When no placeholder is presented, the application is locked to OOB mode.
