Twitter OAuth (PHP): Need good, basic example to get started

Using Facebook's PHP SDK, I was able to get Facebook login working pretty quickly on my website. They simply set a $user variable that can be accessed very easily.

I've had no such luck trying to get Twitter's OAuth login working... quite frankly, their github material is confusing and useless for someone that's relatively new to PHP and web design, not to mention that many of the unofficial examples I've tried working through are just as confusing or are outdated.

I really need some help getting Twitter login working--I mean just a basic example where I click the login button, I authorize my app, and it redirects to a page where it displays the name of the logged in user.

I really appreciate your help.

EDIT I'm aware of the existence of abraham's twitter oauth but it provides close to no instructions whatsoever to get his stuff working.

Solution

I just tried abraham's twitteroauth from github and it seems to work fine for me. This is what I did

git clone https://github.com/abraham/twitteroauth.git
Upload this into your webhost with domain, say, www.example.com
Go to Twitter Apps and register your application. The changes that you need are (assuming that you will use abraham's twitteroauth example hosted at http://www.example.com/twitteroauth)
a) Application Website will be http://www.example.com/twitteroauth
b) Application type will be browser
c) Callback url is http://www.example.com/twitteroauth/callback.php (Callback.php is included in the git source)
Once you do this, you will get the CONSUMER_KEY and CONSUMER_SECRET which you can update in the config.php from the twitteroauth distribution. Also set the callback to be the same as http://www.example.com/twitteroauth/callback.php

Thats it. If you now navigate to http://www.example.com/twitteroauth, you will get a "Signin with Twitter", that will take you to Twitter , authorize the request and get you back to the index.php page.

EDIT: Example will not work but do not worry. Follow the above steps and upload to server. Make sure you rename the file from github repository i.e. config-sample.php->config.php
