Facebook Graph API Consumer in namespaced, easy to test PHP, continuously integrated with Travis CI.

Installation

The easiest way - via packagist and composer:

{
    "require": {
        "nixilla/facebook-api-consumer": "~0.1"
    }
}

What does it do?

This library is a wrapper around Facebook Graph API plus it provides some utils method often used in Facebook integrated applications.

How does it do it?

This library provides Facebook\Consumer class which is a higher level wrapper around kriswallsmith/buzz library. You just specify what end point you're interested in and it'll pull the information for you.

For example:

<?php

require_once './vendor/autoload.php';

$client = new Buzz\Browser(new Buzz\Client\Curl());
$consumer = new Facebook\Consumer($client);

$consumer->setAccessToken('ACCESS_TOKEN_STRING');

$result = $consumer->call('/me/feed');

By default the Facebook\Consumer converts the json output from Facebook API to PHP array. It does it using Facebook\DefaultConverter class.

However you can change this behaviour by injecting your custom converter. All you need to do is to create you converter class that implements Facebook\Converter interface and inject into Facebook\Consumer.

For example if you are using Symfony 2 and have AcmeDemoBundle:User class and you want Facebook\Consumer to output that class, you need to:

<?php

# src/Acme/DemoBundle/Converter/UserConverter.php
namespace Acme\DemoBundle\Converter;

use Facebook\Converter;
use Acme\DemoBundle\Entity\User;

class UserConverter implements Converter
{
    public function convert($json_string)
    {
        // do whatever you need to do, for example
        $user = new User()
        $user->fromArray(json_decode($json_string, true));

        return $user;
    }
}

<?php

# src/Acme/DemoBundle/Controller/UserController.php

namespace Acme\DemoBundle\Converter;

use Acme\DemoBundle\Converter\UserConverter;

class UserController extends Controller
{
    public function newAction(Request $request)
    {
        $consumer = $this->container->get('facebook.consumer');
        $consumer->setAccessToken($this->container->get('security.context')->getToken()->getAccessToken());
        $consumer->setConverter('/me', new UserConverter());

        $user = $consumer->call('/me');

        // you can now use it for forms
        $form = $this->createForm(new UserType(), $user);
    }
}
