This is an unofficial version of Facebook's PHP SDK designed for PHP 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 8.1 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 (v6 and v7 only): 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';

use Facebook\Facebook;
use Facebook\GraphNodes\GraphUser;
use Facebook\Exceptions\FacebookResponseException;
use Facebook\Exceptions\FacebookSDKException;

$fb = new Facebook([
 'app_id' => '{app-id}',
 'app_secret' => '{app-secret}',
 'default_graph_version' => 'v20.0',
 //'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 {

 // If you provided a 'default_access_token', the '{access-token}' is optional.
 $response = $fb->get('/me', '{access-token}');
 
 // To decode the response to a PHP class, provide the class of the root node in the
 // response. You will have to match this manually based on the endpoint you
 // requested. Please do open a pull request if you want to add more types.
 
 /** @var GraphUser $me */
 $me = $response->getGraphNode(GraphUser::class);
 echo 'Logged in as ' . $me->getName() . PHP_EOL;
 echo 'User email is ' . $me->getEmail() . PHP_EOL;
 
} catch (FacebookResponseException $e) {

 // When Graph returns an error
 echo 'Graph returned an error: ' . $e->getMessage();
 
} catch (FacebookSDKException $e) {

 // When validation fails or other local issues
 echo 'Facebook SDK returned an error: ' . $e->getMessage();
 
}

Tests
