Firebase FCM server php-android - php

Question

I created a simple php code to send a notification to my android devices which have google log in method from firebase implementation. Their tokens are already stored in my database. When I execute my php, it doesn't send the notification. Whoever , if i send a notification trough firebase notification console it works. This is my php code .
function sendGCM($message, $registration_ids) {
//FCM URL
$url = "https://fcm.googleapis.com/fcm/send";
//prepare data
$fields = array (
'registration_ids' => array ($registration_ids),
'data' => array ("message" => $message)
);
$fields = json_encode ( $fields );
//header data
$headers = array ('Authorization: key=<YOUR_API_KEY>', 'Content-Type: application/json');
//initiate curl request
$ch = curl_init ();
curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_POST, true );
curl_setopt ( $ch, CURLOPT_HTTPHEADER, $headers );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $fields );
// execute curl request
$result = curl_exec ( $ch );
//close curl request
curl_close ( $ch );
//return output
return $result;
}
Error:
when I execute this php file, throw this error:
{
"multicast_id": 5359746182596118281,
"success": 0,
"failure": 1,
"canonical_ids": 0,
"results": [
{
"error": "InvalidRegistration"
}
]
}

Try this:-
<?php
// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'your_key' );
$registrationIds = array($id); //$id is string not array
// prep the bundle
$notification = array
(
'title' => 'title',
'body' => 'body',
'icon' => 'logo',
'sound' => 'default',
'tag' => 'tag',
'color' => '#ffffff'
);
$data = array
(
'message' => 'message body',
'click_action' => "PUSH_INTENT"
);
$fields = array
(
'registration_ids' => $registrationIds,
'notification' => $notification,
'data' => $data,
'priority' => 'normal'
);
$headers = array
(
'Authorization: key=' . API_ACCESS_KEY,
'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 );
curl_close( $ch );
echo $result;
?>
