2. The same output i want to show in seconds and in HH:MM:SS

Answer 1

For till 23:59:59 hours you can use PHP default function

echo gmdate("H:i:s", 86399);

Which will only return the result till 23:59:59

If your seconds is more then 86399 than with the help of @VolkerK answer

$time = round($seconds);
echo sprintf('%02d:%02d:%02d', ($time/3600),($time/60%60), $time%60);

will be the best options to use ...
