Firebase Cloud Messaging PHP Client

Just another client to send push notifications via Firebase Cloud Messaging (FCM). The implementation is inspired by Paragraph1/php-fcm and its fork guigpm/php-fcm, but heavily reworked in favor of simpler code and better implementation.

Installation

This library relies on PSR-18 which defines how HTTP message should be sent and received. You can use any library to send HTTP messages that implements psr/http-client-implementation. Read more about PSR-18 in this blog.

To install this library with Guzzle you may run the following command:

composer require erickskrauch/fcm guzzlehttp/guzzle

Or using the curl client (you'll need to provide a PSR7 implementation such as nyholm/psr7 if not using Guzzle):

composer require erickskrauch/fcm php-http/curl-client nyholm/psr7

Usage

The component's constructor allows you to explicitly pass all dependencies. But you can also pass only the mandatory API token, and all other dependencies will be found automatically. The example below relies on auto discovery.

use ErickSkrauch\Fcm\Client;
use ErickSkrauch\Fcm\Message\Message;
use ErickSkrauch\Fcm\Message\Notification;
use ErickSkrauch\Fcm\Recipient\Device;

$client = new Client('SERVICE ACCOUNT OAUTH TOKEN', 'project-x146w');

$notification = new Notification(, 'testing body');
$notification->setTitle('Wow, something happened...');
$notification->setBody('It just works!');

$message = new Message();
$message->setNotification($notification);
$message->setCollapseKey('collapse.key');

$recipient = new Device('your-device-token'); // or new ErickSkrauch\Fcm\Recipient\Topic('topic');

$result = $client->send($message, $recipient);

Ensuring code quality

The project has several tools for quality control. All checks are performed in CI, but if you want to perform checks locally, here are the necessary commands:

vendor/bin/php-cs-fixer fix -v
vendor/bin/phpstan analyse
vendor/bin/phpunit
vendor/bin/infection # Try "env XDEBUG_MODE=coverage vendor/bin/infection" in case of errors
