FCM message not delivered to device when sent from php - php

Question

I am trying to implement FCM in my app. Right now, I am able to receive messages when i send them from firebase app console. But when i try to send messages from my php code on the server, the message does not get delivered to the phone. However, I get the message_id with numbers whenever the call to FCM is completed and no indication of any errors. Any help would be appreciated.
PHP code:
public function send_fcm() {
$API_ACCESS_KEY = '*****************************';
$msg = array ('message' => 'here is a message. message',
'title' => 'This is a title. title',
'subtitle' => 'This is a subtitle. subtitle',
'tickerText' => 'Ticker text here...',
'vibrate' => 1,
'sound' => 1
);
$fields = array('to' => '/topics/mytopic',
'priority' => 'high',
'data' => $msg);
$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));
$pushResult = curl_exec($ch);
curl_close($ch);
}

Answer 1

you should provide notification with fields array , I use this method to send notification using PHP
public static function toDevice($token , $message)
{
$url = 'https://fcm.googleapis.com/fcm/send';
$fields = array (
'to' => $token,
'notification' => [
"body" => $message ,
...
] ,
"data" => [
...
]
);
$fields = json_encode ( $fields );
$headers = array (
'Authorization: key=' . "XXXXXXXXXXXXXXXXXXX",
'Content-Type: application/json'
);
$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 );
$result = curl_exec ( $ch );
curl_close ( $ch );
return $result;
}

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$result = curl_exec($ch);
if ($result === FALSE) {
die('CURL FAILED ' . curl_error($ch));
}
$info = curl_getinfo($ch);
curl_close($ch);
return array('result' => $result, 'status' => $info['http_code']);
