Convert seconds into days, hours, minutes and seconds

Question

I would like to convert a variable $uptime which is seconds, into days, hours, minutes and seconds.

Example:

Answer 1

function seconds_to_time($seconds){
     // extract hours
    $hours = floor($seconds / (60 * 60));

    // extract minutes
    $divisor_for_minutes = $seconds % (60 * 60);
    $minutes = floor($divisor_for_minutes / 60);

    // extract the remaining seconds
    $divisor_for_seconds = $divisor_for_minutes % 60;
    $seconds = ceil($divisor_for_seconds);

    //create string HH:MM:SS
    $ret = $hours.":".$minutes.":".$seconds;
    return($ret);
}
