Simplified version of Facebook Graph SDK

Version: 1.0.0

Usage of Unofficial Facebook Graph SDK

This application requires the Google My Business API v4.0

1. Installation

First, install the SDK via Composer:

composer require abdulbaquee/facebook-graph-sdk

2. Basic Setup

Start by including the autoload file and initializing the SDK:

require 'vendor/autoload.php';

use Facebook\GraphSDK\OAuth;
use Facebook\GraphSDK\BaseClient;

$oauth = new OAuth('your-app-id', 'your-app-secret', 'your-redirect-uri', 'graph-version');

3. Authentication

Redirect the user to Facebook's login page to get an authorization code:

$loginUrl = $oauth->getLoginUrl(['email', 'public_profile']);
header('Location: ' . $loginUrl);
exit;

After the user authorizes, handle the callback to obtain an access token:

if (isset($_GET['code'])) {
    $accessToken = $oauth->getAccessTokenFromCode($_GET['code']);
    echo 'Access Token: ' . $accessToken;
}

4. Making API Requests

Use the BaseClient to make requests to the Facebook Graph API:

$client = new BaseClient($accessToken);
$response = $client->get('/me?fields=id,name,email');
$user = $response->getBody();

echo 'ID: ' . $user['id'];
echo 'Name: ' . $user['name'];
echo 'Email: ' . $user['email'];

5. Batch Requests

For multiple requests in a single call:

$batch = [
    $client->createRequest('GET', '/me?fields=id,name'),
    $client->createRequest('GET', '/me/friends'),
];

$batchResponse = $client->sendBatchRequest($batch);

foreach ($batchResponse->getResponses() as $response) {
    print_r($response->getBody());
}

6. Error Handling

Handle errors gracefully using exceptions:

try {
    $response = $client->get('/me?fields=id,name');
} catch (FacebookSDKException $e) {
    echo 'Error: ' . $e->getMessage();
}
