Push Notifications for Android Using PHP: A Guide

Learn how to send push notifications to Android devices using PHP in this guide. Set up your Firebase project and configure your app to receive push notifications.

Push notifications are a powerful tool for keeping your Android app users engaged and informed. With push notifications, you can send timely and relevant messages to your users, even when they're not actively using your app. In this step-by-step guide, we'll show you how to send push notifications to Android devices using PHP.

Step 1: Create a Firebase Project

To send push notifications to Android devices, you'll need to have a Firebase project. If you don't have one already, you can create one for free on the Firebase website.

Step 2: Set Up Your App for Push Notifications

Before you can send push notifications, you'll need to configure your app to receive them. To do this, you'll need to add the Firebase SDK to your app and configure your app's package name and Firebase Cloud Messaging (FCM) server key.

Step 3: Set Up Your PHP Server

To send push notifications from your PHP server, you'll need to have the following:

  • A valid SSL certificate
  • An FCM server key
  • The Firebase PHP library

Once you have these items, you can start setting up your PHP server. You'll need to install the Firebase PHP library, which will allow you to connect to the FCM server and send push notifications.

Step 4: Write Your PHP Code

To send a push notification from your PHP server, you'll need to write some code. Here's an example of what your code might look like:


$serverKey = 'your_server_key';
$deviceToken = '1234567890123456789012345678901234567890123456789012345678901234';

$notification = array(
    'title' => 'Hello, world!',
    'body' => 'This is a test notification.',
    'icon' => 'myicon'

$fields = array(
    'to' => $deviceToken,
    'notification' => $notification

$headers = array(
    'Authorization: key=' . $serverKey,
    'Content-Type: application/json'

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
$result = curl_exec($ch);


In this example, we're sending a push notification with the title "Hello, world!" and the message "This is a test notification." to the device with the token '1234567890123456789012345678901234567890123456789012345678901234'. You'll need to replace this device token with the token for the device you want to send the notification to, and replace 'your_server_key' with your FCM server key.

Step 5: Test Your Code

Once you've written your code, you'll need to test it to make sure it's working correctly. You can use a tool like the Firebase Console to send a test notification to your app.

Step 6: Send Push Notifications to Your Users

Now that you've tested your code and it's working correctly, you can start sending push notifications to your users. You'll need to write a script that reads your user database and sends a notification to each user's device token.


Sending push notifications to Android devices using PHP is a powerful way to keep your users engaged and informed. By following these steps, you can easily set up your PHP server and start sending push notifications to your users.
