How to send push notifications to multiple devices using php script using FCM?

Question

I\'m new to push notifications using FCM from php to Android devices. From android side I have generated FCM reg_id & send it over php script & store into mysql data

If you were to send notification via terminal the data part of the curl command would look like this:

{
"registration_ids": ["device_token_1", "device_token_2"],
"notification": {
    "body": "Hello",
    "title": "Hello",
    "vibrate": 1,
    "sound": 1
 }
}

PHP code:

$body = array(
        'registration_ids' => array("device_token_1", "device_token_2"),
        'notification' => array('body' => 'Hello', 'title' => 'Hello', 'vibrate' => 1, 'sound' => 1)
    );
