APNS with Google App Engine and PHP SSL error - php

Question

I am trying to send iOS push notifications from a PHP App Engine backend but I am receiving the following errors. I am not sure if there is a problem with the certificate, the way I'm doing it, or something specific to App Engine. This is my first time sending push notifications to iOS.
Here is my code :
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
$fp = stream_socket_client(
'ssl://gateway.sandbox.push.apple.com:2195', $err,
$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp)
{
//Handle Error
}
$body['aps'] = array(
'alert' => $data["message"],
'sound' => 'default',
);
$body["postID"] = $data["postID"];
$body["groupID"] = $data["groupID"];
$body["type"] = $data["type"];
$payload = json_encode($body);
foreach ($registrationIds as $registrationID)
{
$deviceToken = $registrationID;
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;
$result = fwrite($fp, $msg, strlen($msg));
}
fclose($fp);
Here is the error I get :
PHP Warning: stream_socket_client(): SSL operation failed with code 1. OpenSSL
Error messages: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake
failure in fakefile.php
I have no idea what the cause is. Thanks in Advance
UPDATE :
That is no longer the error I get. Now I get this :
PHP Warning: stream_socket_client(): unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Unknown error)

Answer 1

May be your port 2195 and 2196 are closed from server side that are blocking push notifications.

Answer 2

In stream_context_set_option you did not include the full path to the ck.pem file . After giving the full path there was no error.
Following is code may help to solve your problem.
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', '/Users/Development/Dev/ck.pem');
Following code for checking port is enable for Push notification.
<?php
chkServer('gateway.sandbox.push.apple.com', 2195);
//chkServer('gateway.push.apple.com',2195);
function chkServer($host, $port)
{
$hostip = #gethostbyname($host);
if ($hostip == $host) {
echo "Server is down or does not exist";
} else {
if (!$x = #fsockopen($hostip, $port, $errno, $errstr, 5)) {
echo "Port $port is closed.";
} else {
echo "Port $port is open.";
if ($x) {
#fclose($x);
}
}
}
}
?>
Happy coding.
