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 database. Now, I would like to send notifications from php script to multiple android devices simultaneously.
Here is the php scripts that are used during sending push notifications :
1.firebase.php (reference link)
<?php
class Firebase {
// sending push message to single user by firebase reg id
public function send($to, $message) {
$fields = array(
'to' => $to,
'data' => $message,
);
return $this->sendPushNotification($fields);
}
// sending push message to multiple users by firebase registration ids
public function sendMultiple($registration_ids, $message) {
$fields = array(
'registration_ids' => $registration_ids,
'data' => $message,
);
return $this->sendPushNotification($fields);
}
// function makes curl request to firebase servers
private function sendPushNotification($fields) {
require_once('config.php');
// Set POST variables
$url = 'https://fcm.googleapis.com/fcm/send';
$headers = array(
'Authorization: key=' . FIREBASE_API_KEY,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Disabling SSL Certificate support temporarly
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
// Execute post
$result = curl_exec($ch);
// echo "Result".$result;
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
// Close connection
curl_close($ch);
return $result;
}
}
?>
2.push.php : (reference link)
<?php
class Push {
// push message title
private $title;
private $message;
private $image;
// push message payload
private $data;
// flag indicating whether to show the push
// notification or not
// this flag will be useful when perform some opertation
// in background when push is recevied
private $is_background;
function __construct() {
}
public function setTitle($title) {
$this->title = $title;
}
public function setMessage($message) {
$this->message = $message;
}
public function setImage($imageUrl) {
$this->image = $imageUrl;
}
public function setPayload($data) {
$this->data = $data;
}
public function setIsBackground($is_background) {
$this->is_background = $is_background;
}
public function getPush() {
$res = array();
$res['data']['title'] = $this->title;
$res['data']['is_background'] = $this->is_background;
$res['data']['message'] = $this->message;
$res['data']['timestamp'] = date('Y-m-d G:i:s');
return $res;
}
}
3.test.php
<?php
include_once('config.php');
require_once('DB_Functions.php');
require_once('firebase.php');
require_once('push.php');
$db = new DB_Functions();
$firebase = new Firebase();
$push = new Push();
if(isset($_POST['send']))
{
// $sendvalue = $_POST['send'];
ChromePhp::log('send it '.$_POST['send']." user
category:".$_POST['user_category']." Title : ".$_POST['message_title']." Message : ".$_POST['message_to_send']);
$ucategory = $_POST['user_category'];
ChromePhp::log('U category '.$ucategory);
// notification title
$messageTitle = isset($_POST['message_title']) ? $_POST['message_title'] : '';
// notification message
$messageToSend = isset($_POST['message_to_send']) ? $_POST['message_to_send'] : '';
ChromePhp::log('Message Title '.$messageTitle." Message:".$messageToSend);
$userslist_with_fcm_id = $db->getUsersFCMId($ucategory);
ChromePhp::log('FCM LIST '.$userslist_with_fcm_id->num_rows);
// var_dump($userslist_with_fcm_id);
$push->setTitle($messageTitle);
$push->setMessage($messageToSend);
$push->setIsBackground(FALSE);
$json = '';
$response = '';
if ($userslist_with_fcm_id->num_rows > 0) {
while ($row = mysqli_fetch_array($userslist_with_fcm_id)){
ChromePhp::log('FCM ID '.$row['fcm_id']);
$json = $push->getPush();
$regId = $row['fcm_id'];
$response = $firebase->send($regId, $json);
}
}
else{
echo '<h3>Oops ! You got empty data</h3>';
}
var_dump($response);
}
?>

So, as of now I have tried to iterate over all reg_ids from database & call send method but it didn't send notifications to any devices .
解决方案
Try to send device ID of multiple devices as an array. In your case,
$registration_ids must be an array of device IDs.
E.g
$registration_ids = array('Device ID 1', 'Device ID 2');
