Facebook PHP SDK — a simple guide!

The Facebook PHP SDK is a powerful library that allows developers to easily integrate Facebook login and make requests to the Graph API. In this post, we’ll go over how to install, initialize and perform operations like posting to timelines, user registrations, logins and more!


Facebook Application Prerequisite

Before we dive in, you’ll need to create an app on Facebook to use the Facebook PHP SDK. You’ll receive an App ID and App Secret that will be needed when initializing the Facebook PHP SDK library. For more information on creating an app, see Facebook’s Register and Configure an App tutorial.

Important: Be sure to update the App Domains setting under Settings > Basic in the App Dashboard.

Pro Tip: In development and/or on your local? Create a test app. Test apps have their own App ID, App Secret and settings. This allows you update App Domains specific to the environment.


Facebook PHP SDK Installation

The Facebook PHP SDK can be installed with Composer:

composer require facebook/graph-sdk

Are you upgrading from v4.x? Facebook PHP SDK v5.x introduced breaking changes. Please read the upgrade guide before upgrading.

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

Facebook PHP SDK Usage

Here’s a simple GET example of how a user’s profile and outputting the user’s name:

require_once __DIR__ . '/vendor/autoload.php'; // change path as needed

$fb = new \Facebook\Facebook([
  'app_id' => '{app-id}',
  'app_secret' => '{app-secret}',
  'default_graph_version' => 'v2.10',
  //'default_access_token' => '{access-token}', // optional
]);

// Use one of the helper classes to get a Facebook\Authentication\AccessToken entity.
//   $helper = $fb->getRedirectLoginHelper();
//   $helper = $fb->getJavaScriptHelper();
//   $helper = $fb->getCanvasHelper();
//   $helper = $fb->getPageTabHelper();

try {
  // Get the \Facebook\GraphNodes\GraphUser object for the current user.
  // If you provided a 'default_access_token', the '{access-token}' is optional.
  $response = $fb->get('/me', '{access-token}');
} catch(\Facebook\Exceptions\FacebookResponseException $e) {
  // When Graph returns an error
  echo 'Graph returned an error: ' . $e->getMessage();
  exit;
} catch(\Facebook\Exceptions\FacebookSDKException $e) {
  // When validation fails or other local issues
  echo 'Facebook SDK returned an error: ' . $e->getMessage();
  exit;
}

$me = $response->getGraphUser();
echo 'Logged in as ' . $me->getName();

That’s the quick and dirty that just about every other post out there on the topic of using the Facebook PHP SDK goes.

    I am getting this error.
    Does this require me to get permissions from facebook for each action mentioned in the Status and Review section of my app.
    Fatal error: Uncaught exception ‘FacebookFacebookPermissionException’ with message ‘(#200) The user hasn’t authorized the application to perform this action’

      Looks like the access token may be incorrect or your session data isn’t getting passed over. Can I see the code you’re using?

    Great article!

    BTW, what happened to the getSession() method from v4 ?

    I have this code and now is useless.

    $helper = new FacebookPageTabHelper();
    $helper = $fb->getPageTabHelper();
    if ($helper->getPageId()) {
    $data[‘page’] = [
    ‘id’ => $helper->getPageId(),
    ‘admin’ => $helper->isAdmin(),
    // ‘liked’ => $helper->isLiked(),
    ‘liked’ => false
    ];
    }
    if ($helper->getSession()) {
    $session = $helper->getSession();
    }

    I would like to thank and commend you on this lesson. It really helped me i have been struggling for months with this Facebook graph. you explained it so clear. Facebook really needs to hire you. I could follow your instructions just fine and my demos all worked first time on version 5. When i follow the Facebook examples in Facebook developer I got lost every time. So THANK YOU!!!!!!

    HI. This is a great article, one of the best explanations i have found in the web about this subject.
    I have a question for you, maybe you now how to solve it.
    Is there any way to get an access token, stright from the php code, having my login information (facebook user, password), so I don’t need to use any login screen? My point is to try to get a token from my php code using the login data as a parameter inside the code. I guess some kind of oauth against facebook server through php..
    Thanks.

    Video is uploading to my own facebook timeline successfully, but if upload from another account it show error of permission.

    I want every user upload to their own timeline.

    Thank you

    May I let you all know Facebook is asking since a little while to redirect the callback to a secured – https – enabled website. Maybe you all were aware of it already. I just found out and wanted to share it with you.

    Happy programming and share your results. I am curious what people were capable of building.

    Thank you and enjoy your day!
