PHP iOS push notifications (APNS) - php

Question

I am using PHP to try to send a push notification to my iOS app. My push code looks like this:
<?php
$title="Notification";
$message=array();
$message['text']="Message";
$message['id']=1;
$to='695D55573361DB9948D09AB43EA1548A9AAECB4D23F7D836BD7F88FA94ABBE5E';
echo $to.PHP_EOL;
sendPushAPN($to,$title,$message);
function sendPushAPN($to,$title,$message)
{
$to=str_replace(" ","",$to);
// Put your device token here (without spaces):
$deviceToken=$to;
// Put your private key's passphrase here:
$passphrase = 'abc';
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'aps.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
// Open a connection to the APNS server
$fp = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp) exit("Failed to connect: $err $errstr" . PHP_EOL);
echo 'Connected to APNS' . PHP_EOL;
// Create the payload body
// codi existent //$body['aps'] = array('alert' => "ole.. alex",'sound'=> 'default','push_type' => 'alert');
$body['aps']=array('alert' => array('title' => 'Notificacion','body' => 'Ok Alex'),'sound' => 'default');
$payload = json_encode($body);
// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;
// $msg = pack("C", 1) . pack("N","alert") . pack("N",$deviceToken) . pack("N", $apple_expiry) . pack("n", 32) . pack('H*', str_replace(' ', '', $deviceToken'])) . pack("n", strlen($payload)) . $payload;
// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));
// Close the connection to the server
fclose($fp);
echo 'Result:' . $result . PHP_EOL;
}
?>
But my output always looks the same:
Connected to APNS
Result:114
and the push notification never arrives. What does 114 code mean? Is there any way to get more information about what is going on? Or perhaps I'm just using a wrong way of sending push notifications?

Answer 1

Your code is using the legacy binary API for APNS.
This is no longer supported.
You need to use the HTTP/2 API.
A quick web search seems to indicate that there are a few different PHP libraries that can provide this as well as sample code.
