Facebook SDK for PHP

This repository contains the open source PHP SDK that allows you to access Facebook Platform from your PHP app.

Usage

This version of the Facebook SDK for PHP requires PHP 5.4 or greater.

Minimal example:

<?php

// Skip these two lines if you're using Composer
define('FACEBOOK_SDK_V4_SRC_DIR', '/path/to/facebook-php-sdk-v4/src/Facebook/');
require __DIR__ . '/path/to/facebook-php-sdk-v4/autoload.php';

use Facebook\FacebookSession;
use Facebook\FacebookRequest;
use Facebook\GraphUser;
use Facebook\FacebookRequestException;

FacebookSession::setDefaultApplication('YOUR_APP_ID','YOUR_APP_SECRET');

// Use one of the helper classes to get a FacebookSession object.
//   FacebookRedirectLoginHelper
//   FacebookCanvasLoginHelper
//   FacebookJavaScriptLoginHelper
// or create a FacebookSession with a valid access token:
$session = new FacebookSession('access-token-here');

// Get the GraphUser object for the current user:

try {
  $me = (new FacebookRequest(
    $session, 'GET', '/me'
  ))->execute()->getGraphObject(GraphUser::className());
  echo $me->getName();
} catch (FacebookRequestException $e) {
  // The Graph API returned an error
} catch (\Exception $e) {
  // Some other error occurred
}
