push notification - Getting errors using APNS PHP

Question

Here's the code I'm using

<?php
$deviceToken = 'my device key';  // not putting in for security

$payload['aps'] = array('alert' => 'This is the alert text', 'badge' => 1, 'sound' => 'default');
$payload = json_encode($payload);

$apnsHost = 'gateway.sandbox.push.apple.com';
$apnsPort = 2195;
$apnsCert = 'apns-dev.pem';

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

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

$apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $deviceToken)) . chr(0) . chr(strlen($payload)) . $payload;
fwrite($apns, $apnsMessage);

socket_close($apns);
fclose($apns);
?>

and I get these errors

Warning: stream_socket_client() [function.stream-socket-client]: Unable to set private key file `apns-dev.pem' in /home/bryan/sendpush.php on line 14

Warning: stream_socket_client() [function.stream-socket-client]: failed to create an SSL handle in /home/bryan/sendpush.php on line 14

I actually now got it down to these errors

Warning: stream_socket_client() [function.stream-socket-client]: SSL operation failed with code 1. OpenSSL Error messages: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure in /home/bryan/PushService.php on line 27

Answer 1

1. Use the absolute path for the private key instead of relative path.

2. Make sure the php user (or webserver user, depending.. www-data, apache, nginx, www...) is allowed to read it (chown, chmod).
