How to send Firebase Cloud Messaging when backend in php?

Question

Android

Hello. I faced such problem. The task is to make notifications in applications on iOS and Android. I first decided to use Firebase Cloud Messaging. Later I found out that Firebase does not work with PHP... The backend of the application is written in PHP.
On the backend, I do only 2 scenarios for notifications:
- Receiving bonuses for certain actions
- Notification of the purchase of goods
Now I'm wondering how I can connect these scripts with Firebase Cloud Messaging in order to send them by pushes to the application .. And the notifications themselves were also stored in the application as a list on a separate screen.
Is there a solution to make an intermediary on js and already connect it with Firebase Cloud Messaging? What do you think?
Thank you in advance for any solutions.

Example:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, htmlspecialchars_decode('https://fcm.googleapis.com/fcm/send'));
curl_setopt($ch, CURLOPT_POST, true);
$headers = [
  'Authorization: key=' . API_ACCESS_KEY,
  'Content-Type: application/json'
];
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 2);

$fields = [
  'to' => 'userAgentToken',
  'notification' => [
  'body' => 'Some body text',
  'title' => 'Some title text'
]];

curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
curl_exec($ch);

curl_close($ch);
