The SitePoint PHP blog has posted a new tutorial showing you how to integrate the HybridAuth library into your application for easy logins via popular social sites like Facebook, Twitter or even Google+.
A trend in many of today's websites is a feature that allows users to sign in via their social network accounts. A classic example is the SitePoint community where users have the option to use their Facebook, Twitter, Google, Yahoo or GitHub account to log in without having to register an account. In this tutorial, we will be learning about HybridAuth - a PHP library that takes the pain out of building a social login feature. HybridAuth acts as an abstract API between your application and the various social APIs and identity providers.
They jump right into things, showing you how to install the library via Composer and configure it to work with a simple Slim-based application. They set up providers for Facebook, Twitter and Google+ and show how to call the "authenticate" method to make the connection. He then starts on the sample application, creating a login page and a database table for user tracking. The process continues showing how to connect the user from the social site to your setup and retrieve their profile information. All the code you'll need is here, including the Slim structure, the database connection setup and the needed templates. You can also find the finished product in this GitHub repository.
