-My PHP script

    // Open a connection to the APNS server

    $fp = stream_socket_client(
        $url, $err,
        $errstr, 2, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
    if (!$fp)
        exit("Failed to connect: $err $errstr" . PHP_EOL);

    echo 'Connected to APNS' . PHP_EOL;
    // Build the binary notification
    $msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

    // Send it to the server
    $result = fwrite($fp, $msg, strlen($msg));

    if (!$result)
        echo 'Message not delivered' . PHP_EOL;
    else
    {
        echo 'Message successfully delivered111' . PHP_EOL;
        $query_update="update wp_apns_messages set status='delivered',delivery=NOW() where pid='$pid'";
        $res_update=mysql_query($query_update) or die(mysql_error());
    }

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