如何使用 FCM 使用 php 脚本向多个设备发送推送通知?

尝试将多个设备的设备 ID 作为数组发送.就你而言，

$registration_ids 必须是一组设备 ID.

例如

$registration_ids = array('设备 ID 1', '设备 ID 2');

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();

if(isset($_POST['send']))

    // $sendvalue = $_POST['send'];
        ChromePhp::log('send it '.$_POST['send']." user

        $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 .

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');
