APNS push notifications not being sent - php

Question

Actually I am new to APNS and I have been using some help from the online forums and blogs. I am using PHP to implement the server side. The following is my PHP code
<?php
// Put your device token here (without spaces):
$deviceToken = '0f744707bebcf74f9b7c25d48e3358945f6aa01da5ddb387462c7eaf61bbad78';
// Put your private key's passphrase here:
$passphrase = 'pushchat';
// 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));
if (!$result)
echo 'Message not delivered' . PHP_EOL;
else
echo '
' . PHP_EOL;
// Close the connection to the server
fclose($fp);
I have converted the .p12 file to a PEM file and named it as ck.pem and has hosted it on the same location as the php file resides. When I execute the PHP file, the following gets printed. Is there something I am missing. I am doubtful about the certificate part.
Connected to APNS
Message successfully delivered

Answer 1

I had the exact same problem, using the exact same example code - works perfect for android but fails for IOS with no returning error.
To fix my problem I had to create the SSL cert again against the app and then run
openssl x509 -in aps_development.cer -inform der -out aps_development.pem
openssl pkcs12 -nocerts -out aps_developmentKey.pem -in ios_development.p12
cat aps_development.pem aps_developmentKey.pem > ck.pem
Finially tested against:
openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert aps_development.pem -key aps_developmentKey.pem -CAfile entrust_2048_ca.cer
After this everything worked perfect, that was on the 29th Sept - Its now stopped working so I think its the Certs again but at least it may help you with your solution.

I actually replaced the UDID of the device with the Device Token and it works like a charm. You cannot use UDID anymore.
