PUSH NOTIFICATIONS

The mini application sends push notifications to all users by country. The push notification contains a title and a message. It sends to the user's device by device token. There are 3 "actions" in the application:

• send saves the push notification in the database and puts it in the queue. We send push notifications by CRON action.
• details displays detailed information about the push notification.
• cron sends the push notification(s) to 100K devices.

What you need to do:

1. Create the necessary tables to save and send push notifications.
2. Implement App\Controllers\PushNotificationController->sendByCountryId()
3. Implement App\Controllers\PushNotificationController->details()
4. Implement App\Controllers\PushNotificationController->cron()

Keep in mind:

• The user can have multiple devices.
• The device token can be expired (expired = 1).
• The cron action runs automatically every minute. So it's 100k devices per 1 minute.
• Use App\models\PushNotification::send() to send a push notification. It returns random value true/false.
• Read the documentation to understand the task: {project}/documentation/index.html
• Use the postman collection for testing: {project}/postman_collection.json
• Feel free to ask about anything if the task is not clear.

Requirements:

PHP 7.4+, PDO and no frameworks/libraries/wrappers, only your code and SQL queries. The app should not only work, but also work fast and safely. Think about the optimization.
