Php – Sending multiple iPhone push notifications + APNS + PHP

apple-push-notificationsiphonePHPpush-notification

I am working on a PHP website + iPhone application and API for iPhone application, has a messaging system for students and doctors, when any one sends message (from website or iPhone) the other user should get push notification on his iphone. For example if student adds a new question for teacher, a push notification on teachers iPhone/iPad will be send to teacher and when teacher replies to student's answer, student will get a push notification.

Since there is no restriction on number of teachers and student registering to website, my question is how to send push messages to registered user's iPhone? I want to send push message as soon as someone replies or adds a question. Please provide me PHP code for sending multiple push messages.
I am saving device token for each user while registration.

When teacher reply to question I am sending mail to student, I want to send a push notification too to student and vice versa so please specify code able to manage error conditions.

Simple way to do it without use any file. You can call it multiple times with different tokeid.

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ckipad.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

$fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', 
    $err, 
    $errstr, 
    60, 
    STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, 
    $ctx);

//if (!$fp)
//exit("Failed to connect amarnew: $err $errstr" . PHP_EOL);

//echo 'Connected to APNS' . PHP_EOL;

// Create the payload body
$body['aps'] = array(
    'badge' => +1,
    'alert' => $message,
    'sound' => 'default'
);

$payload = json_encode($body);

// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));

if (!$result)
    echo 'Message not delivered' . PHP_EOL;
else
    echo 'Message successfully delivered amar'.$message. PHP_EOL;

// Close the connection to the server
fclose($fp);

Android – Does Android support near real time push notification

Firebase Cloud Messaging FCM FAQ is the new version of GCM. It inherits GCM’s core infrastructure to deliver messages reliably on Android, iOS and Chrome. However they'll continue to support GCM because lot of developers are using GCM SDKs today to handle notifications, and client app upgrade takes time.

As of June 26, 2012, Google Cloud Messaging is the preferred way of sending messages to applications running on devices.

Previously (and now deprecated), the service was called Cloud To Device Messaging.

Php – Apple Push Notification with Sending Custom Data

Regardless of the language and library you use, the push notification payload is a JSON payload:

{
    "aps": {
         "badge": 10,
         "alert": "Hello world!",
         "sound": "cat.caf"
    }
}

The aps token is the Apple APN data. You can add custom data to your payload as well:

{
    "aps": {
         "badge": 10,
         "alert": "Hello world!",
         "sound": "cat.caf"
    },
    "job_id": 1
}

When you receive the notification in the app, check for your param in the notification dictionary:

- (void)handleBackgroundNotification:(NSDictionary *)notification
{
    NSDictionary *aps = (NSDictionary *)[notification objectForKey:@"aps"];
    NSMutableString *alert = [NSMutableString stringWithString:@""];
    if ([aps objectForKey:@"alert"])
    {
        [alert appendString:(NSString *)[aps objectForKey:@"alert"]];
    }
    if ([notification objectForKey:@"job_id"])
    {
        // do something with job id
        int jobID = [[notification objectForKey:@"job_id"] intValue];
    }
}

Keep in mind that the total size of the payload is 256 bytes, and that includes, of course, your custom parameters. So you may have to (at risk of reducing readability) call your custom param "ji" instead of "job_id" to squeeze bytes.

All of this is documented in the Local and Push Notification Programming Guide in the iOS documentation. Definitely would recommend a read because it's more complex than it initially sounds (at least, that's what I thought).
