Put Devices ID's in This array
$dv_id [] = array(
'dv_id' => $re['dv_id'],
);
//Loop through your id's array
for ($i = 1; $i < count($dv_id); $i++) {
//Call your send notification function link this
send_notification($dv_id[$i]['dv_id'],$title,$msg);
}
function send_notification($device_id,$title,$message){
// API access key from Google API's Console
// prep the bundle
$msg = array
(
'to'=>$device_id,
'notification' => array('body'=>$message,'title'=>$title,
'click_action'=>'MY_ACTIVITY_1','sound'=>'tone'),
'data' => array('message'=>$message,'title'=>$title)
);
$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( $msg ) );
$result = curl_exec($ch );
curl_close( $ch );
}
