php - Push notification not receiving on iphone

Question

I am using this tutorial to learn push notification.

<?php

// Put your device token here (without spaces):
$deviceToken = '1675ba8bb005740bb514222227f861c30230a81e6eed6bb6b8f353c57831341d';

// Put your private key's passphrase here:
$passphrase = '111134';

// Put your alert message here:
$message = 'My first push notification!';

////////////////////////////////////////////////////////////////////////////////

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

// Open a connection to the APNS server
$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: $err $errstr" . PHP_EOL);

 echo 'Connected to APNS' . PHP_EOL;

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

// Encode the payload as JSON
$payload = json_encode($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));
 echo 'result =' . $result. PHP_EOL;
if (!$result)
echo 'Message not delivered' . PHP_EOL;
else
echo 'Message successfully delivered' . PHP_EOL;

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

I also configure app for push notification. After configuring for push i also recreate provisioning profiles, old delete one, install new profile. I run app it gives me device id and then i connect both server sandbox and production to send push notification with their relative push profiles but still i am not able to receive push notification on my device.

I also install ipusher on my device and check push notification. they are coming from that application.

One strange thing i notice is that i change my application identifier and use any other app id then device token remain same

Now my problem is I am not receiving the push notification on my device.

The problem is not in my profiles. May be the error is php code that i am using because when i use the easy apns on remote server then it sends push notifications. The notifications received time was 6 to 7 hours. I think this is due to network problem on my device side. But now it is working fine after 2 days on production profile. Now notification take no time for delivering on my device but it is taking 30 sec to 5 minutes on some devices.

There can be one more problem if you are not receiving push notifications on your device from other apps too, then you should check your DNS for the connection.

First make sure that you're using:

• The application is compiled with debug/release provision
• your keychain has the devlopment/production push notification certificate

then use the following code (been tested both dev & production)

<?php
// Comment these lines in production mode
ini_set('display_errors','on');
error_reporting(E_ALL);


// Apns config

// true - use apns in production mode
// false - use apns in dev mode
define("PRODUCTION_MODE",false);

$serverId = 1;
$serverName = 'my-server-domain.com';

if(PRODUCTION_MODE) {
$apnsHost = 'gateway.sandbox.push.apple.com';
} else {
$apnsHost = 'gateway.push.apple.com';
}

$apnsPort = 2195;
if(PRODUCTION_MODE) {
// Use a development push certificate 
$apnsCert = $_SERVER['DOCUMENT_ROOT'].'/apns/apns-dominos-development.pem';
} else {
// Use a production push certificate 
$apnsCert = $_SERVER['DOCUMENT_ROOT'].'/apns/apns-dominos-production.pem';
}


// --- Sending push notification ---

// Insert your device token here 
$device_token = "<dc6127d8 dc6127d8 dc6127d8 dc6127d8 dc6127d8 dc6127d8 dc6127d8    dc6127d8>"; // Some Device Token


// Notification content

$payload = array();

//Basic message
$payload['aps'] = array(
'alert' => 'testing 1,2,3..', 
'badge' => 1, 
'sound' => 'default',
);
$payload['server'] = array(
'serverId' => $serverId,
 'name' => $serverName
);
// Add some custom data to notification
$payload['data'] = array(
'foo' => "bar"
);
$payload = json_encode($payload);

$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert);
stream_context_set_option($streamContext, 'ssl', 'passphrase', "");


$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error,      $errorString, 2, STREAM_CLIENT_CONNECT, $streamContext);


$deviceToken = str_replace(" ","",substr($device_token,1,-1));
echo $deviceToken;
$apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '',      $deviceToken)) . chr(0) . chr(mb_strlen($payload)) . $payload;
fwrite($apns, $apnsMessage);


//socket_close($apns);
fclose($apns);
