getting warning messages while sending push notification to multiple iphone device - php

Question

While i am sending push notifications to multiple iphone devices using php webservices i am getting warning messages like :
Warning: stream_socket_client() [function.stream-socket-client]: SSL: crypto enabling timeout in /home/sample_app/pushnotification.php on line 66
Warning: stream_socket_client() [function.stream-socket-client]: Failed to enable crypto in /home/sample_app/pushnotification.php on line 66
Warning: stream_socket_client() [function.stream-socket-client]: unable to connect to ssl://gateway.push.apple.com:2195 (Unknown error) in /home/sample_app/pushnotification.php on line 66
Warning: fclose() expects parameter 1 to be resource, boolean given in /home/sample_app/pushnotification.php on line 79
This is my code :
$message='testing';
$q1="select devicetoken from tbl_devicetokens";
$re1 = mysql_query($q1);
while($row1=mysql_fetch_row($re1))
{
pushMessage($row1[0],$message,'myapp');
}
function pushMessage($deviceToken,$message,$app) {
echo "Sending iPhone Push Notifications to " . $deviceToken . "<br /><br />";
echo "Your Message: " . $message . "<br /><br />";
$time = time();
$apnsHost = 'gateway.push.apple.com';
$apnsPort = 2195;
$apnsCert = 'apns-myapp.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, $streamContext);
if($apns) {
$payload = array();
$payload['aps'] = array('alert' => $message, 'badge' => 0, 'sound' => 'default');
$payload = json_encode($payload);
$apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $deviceToken)) . chr(0) . chr(strlen($payload)) . $payload;
fwrite($apns, $apnsMessage);
} else {
echo "Connection Failed - iPhone Push Notifications Server";
echo $errorString."<br />";
echo $error."<br />";
}
//socket_close($apns);
fclose($apns);
}
So, can any one tell me how to solve this problem

Answer 1

might seem like a dumb answer, but have you tried your firewall / iptables? Those errors without further information look like connection issues to me. First thing you need to resolve is the timeout problem.

Answer 2

Does this still happen when you push a single notification to a single device?
If it does:
Are you sure that you have the correct path to the certs?
Make sure that the cert file name does not contain other than alphabetic characters.
If not:
Make sure that you are using the correct cert for the correct device environment (development, production)
If a device is jailbroken it will not receive push notifications.
