How can I send push notification to multiple devices in one go in iPhone?

I want to send same messages to all devices who are registered with application but how can send them without making multiple connections...

My current PHP 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, $ctx);  
if (!$fp)
{
  print "Failed to connect $err $errstr\n";
  return;
}
$msg = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack("n",strlen($payload)) . $payload;
fwrite($fp, $msg);

Bottom line, you can't. You need to send a message to each token.

Its not working like a email where you can have multiple recipients.

Once the connection is open you can send a bunch of messages, thats also the preferred way (based on Apples SDK).

from the SDK:

http://developer.apple.com/library/mac/#documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CommunicatingWIthAPS/CommunicatingWIthAPS.html#//apple_ref/doc/uid/TP40008194-CH101-SW2

You should also retain connections with APNs across multiple notifications. APNs may consider connections that are rapidly and repeatedly established and torn down as a denial-of-service attack. Upon error, APNs closes the connection on which the error occurred.

You can use one connection to send multiple messages, so you don't need to open multiple connections. You can't use one message for multiple devices.
