The Facebook Platform is a set of APIs that make your application more social. Read more about integrating Facebook with your web site on the Facebook developer site.

This repository contains the open source PHP SDK that allows you to utilize the above on your website. Except as otherwise noted, the Facebook PHP SDK is licensed under the Apache Licence, Version 2.0 (http://www.apache.org/licenses/LICENSE-2.0.html)

The examples are a good place to start. The minimal you'll need to have is:

<?php

require './facebook.php';

$facebook = new Facebook(array(
  'appId'  => 'YOUR APP ID',
  'secret' => 'YOUR API SECRET',
  'cookie' => true, // enable optional cookie support
));

To make API calls:

try {
  $me = $facebook->api('/me');
} catch (FacebookApiException $e) {
  error_log($e);
}

Logged in vs Logged out:

if ($facebook->getSession()) {
  echo '<a href="https://raw.githubusercontent.com/liuliu/php-sdk/master/' . $facebook->getLogoutUrl() . '">Logout</a>';
} else {
  echo '<a href="https://raw.githubusercontent.com/liuliu/php-sdk/master/' . $facebook->getLoginUrl() . '">Login</a>';
}

We are relying on the GitHub issues tracker linked from above for feedback. File bugs or other issues here.

In order to keep us nimble and allow us to bring you new functionality, without compromising on stability, we have ensured full test coverage of the new SDK. We are including this in the open source repository to assure you of our commitment to quality, but also with the hopes that you will contribute back to help keep it stable. The easiest way to do so is to file bugs and include a test case.
