How To Send Fcm Notification Using Php?

I tried to send FCM using PHP code/web browser. But the problem is when I send it using PHP web browser: FCM notification only appear on virtual devices. FCM notification does no

Solution 1:

By the following way you can send push notification to mobile using google FCM. For me its works as expected. Add the key 'priority' => 'high'

functionsendPushNotification($fields = array())
{
    $API_ACCESS_KEY = 'YOUR KEY';
    $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( $ch );
    return$result;
}

$title = 'Whatever';
$message = 'Lorem ipsum';
$fields = array
(
    'registration_ids'  => ['deviceID'],
    'data'          => '',
    'priority' => 'high',
    'notification' => array(
        'body' => $message,
        'title' => $title,
        'sound' => 'default',
        'icon' => 'icon'
    )
);

sendPushNotification($fields);

Solution 2:

you can create function which send push notification for devices .

// firebase access key
define( 'API_ACCESS_KEY', 'AAAAAG78XmM:APA91bFRHpzuEIgiQRmPUm4uRy8bygNGr1h2Oq3ydc5WtKbrfJA8NVAaGIAxbQELfcOWwN2OR4pf5NzSRuuWOYj_P-XXXXXXXX');        
// target device 'fcm' id$device[0]='JI8YHo7GEo:APA9-aGWOU3U3CXXXXXXXXXXX';
$device[1]='JI8YHo7GEo:APA9-aGWOU3U3CXXXXXXXXXXX';

    $url = 'https://fcm.googleapis.com/fcm/send';

    // "to": "e1w6hEbZn-8:APA91bEUIb2JewYCIiApsMu5JfI5Ak...",   // for single device (insted of "registration_ids"=>"$device"  )$data = array("registration_ids" => $device,            // for multiple devices "notification" => array( 
        "title" => "Party Night", 
        "body" => "Invitation for pool party!",
        "message"=>"Come at evening...",
        'icon'=>'https://www.example.com/images/icon.png'
    ),
        "data"=>array(
        "name"=>"xyz",
        'image'=>'https://www.example.com/images/minion.jpg'
        ) 
    ); 

    $data_string = json_encode($data); 
    $headers = array ( 'Authorization: key=' . API_ACCESS_KEY, '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, $data_string); 
    $result = curl_exec($ch); 

for more details refer this

to – Type String – (Optional) [Recipient of a message] The value must be a single registration token, notification key, or topic. Do not set this field when sending to multiple topics

registration_ids – Type String array – (Optional) [Recipients of a message] Multiple registration tokens, min 1 max 1000.

priority– Type String – (Optional) [ default normal] Allowed values normal and high.

delay_while_idle – Type boolean – (Optional) [default value false] true indicates that the message should not be sent until the device becomes active.

time_to_live – Type JSON number – (Optional) [default value 4 week maximum 4 week] This parameter specifies how long (in seconds) the message should be kept in FCM storage if the device is offline

data – Type JSON Object Specifies the custom key-value pairs of the message’s payload. eg. {“post_id”:”1234″,”post_title”:”A Blog Post Title”}

Solution 3:

In Android you can receive it in onMessageReceived() as Map data…

When in the background – Apps receive the notification payload in the notification tray, and only handle the data payload when the user taps on the notification.

When in the foreground – App receives a message object with both payloads available.

publicclassFcmMessageServiceextendsFirebaseMessagingService{
@Override
publicvoidonMessageReceived(RemoteMessage remoteMessage) {
    //onMessageReceived will be called when ever you receive new message from server.. (app in background and foreground )
    Log.d("FCM", "From: " + remoteMessage.getFrom());

    if(remoteMessage.getNotification()!=null){
    Log.d("FCM", "Notification Message Body: " + remoteMessage.getNotification().getBody());
    }

    if(remoteMessage.getData().containsKey("post_id") && remoteMessage.getData().containsKey("post_title")){
        Log.d("Post ID",remoteMessage.getData().get("id").toString());
        Log.d("Post Title",remoteMessage.getData().get("post_title").toString());
        // eg. Server Send Structure data:{"post_id":"12345","post_title":"A Blog Post"}
    }
}}
