Apple disconnected me because of invalid tokens - php

Question

I try to send multiple notifications with one hit. Many users have more than one device and i put their device tokens into an array. It is working fine but if there is a wrong token Apple is disconnecting me and the device with working token gets no push notification. I've read about a error-response-solution at this post: Apple Push Notification Limits
But this solution is not working for me. It says: Status:7-Invalid payload size.
But there is only the message "test" and I'm sure the reason is the wrong token. How could I continue the foreach script without disconnecting?
// Put your device token here (without spaces):
$deviceToken = array('WRONG_TOKEN', 'WORKING_TOKEN');
// Put your private key's passphrase here:
$passphrase = 'PASS';
// Put your alert message here:
$message = "test";

$fp = stream_socket_client(

exit("Failed to connect: $err $errstr" . PHP_EOL);

// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => "www/sound.mp3",

// Encode the payload as JSON
$payload = json_encode($body);
//foreach für array

$msg = chr(0) . pack('n', 32) . pack('H*', $token) . pack('n', strlen($payload)) . $payload;
// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));
}//foreach end
if (!$result)
echo 'Message not delivered' . PHP_EOL;

echo 'Message successfully delivered' . PHP_EOL;

// Close the connection to the server
fclose($fp);
