We've released version 4 of the Facebook SDK for PHP here: https://github.com/facebook/facebook-php-sdk-v4 Please use the new repository for new projects and contributions. See the Facebook Developers site for documentation.

Facebook PHP SDK (v.3.2.3) (DEPRECATED)

The Facebook Platform is a set of APIs that make your app more social.

This repository contains the open source PHP SDK that allows you to access Facebook Platform from your PHP app. Except as otherwise noted, the Facebook PHP SDK is licensed under the Apache Licence, Version 2.0 (https://www.apache.org/licenses/LICENSE-2.0.html).

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

require 'facebook-php-sdk/src/facebook.php';

$facebook = new Facebook(array(
  'appId'  => 'YOUR_APP_ID',
  'secret' => 'YOUR_APP_SECRET',
));

// Get User ID
$user = $facebook->getUser();

To make API calls:

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

You can make api calls by choosing the HTTP method and setting optional parameters:

$facebook->api('/me/feed/', 'post', array(
	'message' => 'I want to display this message on my wall'
));

Login or logout url will be needed depending on current user state.

if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $loginUrl = $facebook->getLoginUrl();
}

With Composer:

• Add the "facebook/php-sdk": "@stable" into the require section of your composer.json.
• Run composer install.
• The example will look like

if (($loader = require_once __DIR__ . '/vendor/autoload.php') == null)  {
  die('Vendor directory not found, Please run composer install.');
}

$facebook = new Facebook(array(
  'appId'  => 'YOUR_APP_ID',
  'secret' => 'YOUR_APP_SECRET',
));

// Get User ID
$user = $facebook->getUser();

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 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.

The tests can be executed by using this command from the base directory:

phpunit --stderr --bootstrap tests/bootstrap.php tests/tests.php
