This is my php code to fire a push notificaiton.

    foreach ($deviceTokens as $deviceToken) {
        try {
                $msg = chr(0) . pack('n', 32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack('n', strlen($payload)) . $payload;
                $result = fwrite($fp, $msg, strlen($msg));
        } catch (Exception $e) {
                        continue;
        }
     }

the problem is due to some bad tokens notification is fired, but device is not receive that push notification.

In example 4th device token is bad token or expired token. 93e7b09753d3062ec0c0fd8ec89a920ee0918f9e484f5b6d72e7f4a3f7323x07.

so foreach loop fire notification for all devices , and i also print the result , it is printing the result upto last device, but devices token after 4th token not receive notification.

If i remove the 4th device token from the list then all the device receive the token, upto the last device token.

Is there any solution for this??
