PHP Firebase Cloud Messaging

PHP API for Firebase Cloud Messaging from Google.

This library supports Messages/Notifications via HTTP only.

Requires PHP 7.1, if you have to rely on lower version, use original PHP FCM library or some clone of it.

Send message to Device or Topic

<?php
use granam\FirebaseCloudMessaging\FcmClient;
use granam\FirebaseCloudMessaging\FcmMessage;
use granam\FirebaseCloudMessaging\Target\FcmTopicTarget;
use granam\FirebaseCloudMessaging\Target\FcmDeviceTarget;
use granam\FirebaseCloudMessaging\AndroidFcmNotification;

$client = new FcmClient(new \GuzzleHttp\Client(), '_YOUR_SERVER_KEY_');
$message = new FcmMessage(new FcmDeviceTarget('_YOUR_DEVICE_TOKEN_'));
$message->setPriority('high')
    ->setNotification(new AndroidFcmNotification('A message from Foo!', 'Hi Bar, how are you?'))
    ->setData(['photo' => 'https://example.com/photos/Foo.png']);
// you can NOT combine multiple recipient types as topic and device in a single message
$messageForTopic = new FcmMessage(new FcmTopicTarget('_YOUR_TOPIC_'));
$messageForTopic
    ->setNotification(new AndroidFcmNotification('Foo is looking for you!', 'Here you are!'))
    ->setData(['map' => 'https://example.com/maps/foo']);

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

Send silent push notification to a device

App will have to process the notification by its own as system will not show it.

<?php
use granam\FirebaseCloudMessaging\FcmClient;
use granam\FirebaseCloudMessaging\FcmMessage;
use granam\FirebaseCloudMessaging\Target\FcmDeviceTarget;

$client = new FcmClient(new \GuzzleHttp\Client(), '_YOUR_SERVER_KEY_');
$message = new FcmMessage(new FcmDeviceTarget('_YOUR_DEVICE_TOKEN_'));
$message->setData([
        'title' => 'A message from Foo!',
        'message' => 'Hi Bar, how are you?',
        'photo' => 'https://example.com/photos/Foo.png'
    ]);
$response = $client->send($message);
var_dump($response);

Send message to multiple Devices

<?php
use granam\FirebaseCloudMessaging\FcmMessage;
use granam\FirebaseCloudMessaging\Target\FcmDeviceTarget;
use granam\FirebaseCloudMessaging\IosFcmNotification;

$message = new FcmMessage(new FcmDeviceTarget('_YOUR_DEVICE_TOKEN_'));
$message->addTarget(new FcmDeviceTarget('_YOUR_DEVICE_TOKEN_2_'))
    ->addTarget(new FcmDeviceTarget('_YOUR_DEVICE_TOKEN_3_'))
    ->setPriority('high')
    ->setNotification(new IosFcmNotification('You are wanted', 'We got some issue here, where are you? We need you.'))
    ->setData(['attachment' => 'data:image/gif;base64,FooBar==']);
// ...

Send message to multiple Topics

See Firebase documentation for sending to combinations of multiple topics.

<?php
use granam\FirebaseCloudMessaging\FcmMessage;
use granam\FirebaseCloudMessaging\JsFcmNotification;
use granam\FirebaseCloudMessaging\Target\FcmTopicTarget;

$message = new FcmMessage(new FcmTopicTarget('_YOUR_TOPIC_'));
$message->addTarget(new FcmTopicTarget('_YOUR_TOPIC_2_'))
    ->addTarget(new FcmTopicTarget('_YOUR_TOPIC_3_'))
    ->setPriority('high')
    ->setNotification(new JsFcmNotification('some title', 'some body'))
    ->setData(['key' => 'value'])
    // will send to devices subscribed to topic 1 AND topic 2 or 3
    ->setCondition('%s && (%s || %s)');

Subscribe user to the topic

<?php
use granam\FirebaseCloudMessaging\FcmClient;

$client = new FcmClient(new \GuzzleHttp\Client(), '_YOUR_SERVER_KEY_');
$response = $client->subscribeToTopic('_SOME_TOPIC_', ['_FIRST_DEVICE_TOKEN_', '_SECOND_DEVICE_TOKEN_']);
var_dump($response->getStatusCode());
var_dump($response->getBody()->getContents());

Remove user subscription from the topic

<?php
use granam\FirebaseCloudMessaging\FcmClient;

$client = new FcmClient(new \GuzzleHttp\Client(), '_YOUR_SERVER_KEY_');

$response = $client->unsubscribeFromTopic('_SOME_TOPIC_', ['_FIRST_DEVICE_TOKEN_', '_SECOND_DEVICE_TOKEN_']);
var_dump($response->getStatusCode());
var_dump($response->getBody()->getContents());
