Facebook SDK for PHP

Build Status Latest Stable Version Downloads

This is an unofficial version of Facebook's PHP SDK designed for PHP 7/8+. It is being maintained and tested against the newest PHP versions. You can use this in place of version 5.x of Facebook's deprecated facebook/graph-sdk package.

PHP 7.3 is required.

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

Installation

The Facebook PHP SDK can be installed with Composer. Run this command:

composer require nickdnk/graph-sdk

By default, the request will be made via a Facebook\HttpClients\FacebookHttpClientInterface. The default implementation depends on the available PHP extension/packages. In order of priority:

  1. Package guzzlehttp/guzzle (version 6 or 7): Facebook\HttpClients\FacebookGuzzleHttpClient
  2. ext-curl: Facebook\HttpClients\FacebookCurlHttpClient
  3. Fallback: Facebook\HttpClients\FacebookStreamHttpClient

Usage

Simple GET example of a user's profile.

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();

Complete documentation, installation instructions, and examples are available here.

Tests

  1. Composer is a prerequisite for running the tests. Install composer globally, then run composer install to install required files.
  2. Create a test app on Facebook Developers, then create tests/FacebookTestCredentials.php from tests/FacebookTestCredentials.php.dist and edit it to add your credentials.
  3. The tests can be executed by running this command from the root directory:
$ ./vendor/bin/phpunit

By default, the tests will send live HTTP requests to the Graph API. If you are without an internet connection you can skip these tests by excluding the integration group.

$ ./vendor/bin/phpunit --exclude-group integration
