PHP Firebase Cloud Messaging

PHP API for Firebase Cloud Messaging from Google.

Currently this app server library only supports sending Messages/Notifications via HTTP.

See original Firebase docs: https://firebase.google.com/docs/

#Setup
Install via Composer:

composer require sngrl/php-firebase-cloud-messaging

Or add this to your composer.json and run "composer update":

"require": {
    "sngrl/php-firebase-cloud-messaging": "dev-master"
}

#Send message to Device

use sngrl\PhpFirebaseCloudMessaging\Client;
use sngrl\PhpFirebaseCloudMessaging\Message;
use sngrl\PhpFirebaseCloudMessaging\Recipient\Device;
use sngrl\PhpFirebaseCloudMessaging\Notification;

$server_key = '_YOUR_SERVER_KEY_';
$client = new Client();
$client->setApiKey($server_key);
$client->injectGuzzleHttpClient(new \GuzzleHttp\Client());

$message = new Message();
$message->addRecipient(new Device('_YOUR_DEVICE_TOKEN_'));
$message
    ->setNotification(new Notification('some title', 'some body'))
    ->setData(['key' => 'value'])
;

$response = $client->send($message);
var_dump($response->getStatusCode());

#Send message to Topic
Currently sending to topics only supports a single topic as recipient. Mutliple topic as outlined
in the google docs don't seem to work, yet.

use sngrl\PhpFirebaseCloudMessaging\Client;
use sngrl\PhpFirebaseCloudMessaging\Message;
use sngrl\PhpFirebaseCloudMessaging\Recipient\Topic;
use sngrl\PhpFirebaseCloudMessaging\Notification;

$server_key = '_YOUR_SERVER_KEY_';
$client = new Client();
$client->setserver_key($server_key);
$client->injectGuzzleHttpClient(new \GuzzleHttp\Client());

$message = new Message();
$message->addRecipient(new Topic('_YOUR_TOPIC_'));
$message
    ->setNotification(new Notification('some title', 'some body'))
    ->setData(['key' => 'value'])
;

$response = $client->send($message);
var_dump($response->getStatusCode());
