how to convert seconds to time format ?

Question

hi there for some reason i convert a time format like : 03:30 to seconds 3*3600 + 30*60 , now .. i wanna convert it back to it's first ( same ) format upthere ... how could that be ?

My attempt :

3*3600 + 30*60 = 12600 12600 / 60 = 210 / 60 = 3.5 , floor(3.5) = 3 = hour

now .. what about the minutes ??

considering the value can be like 19:00 or 02:51 ... i think you got the picture

and by the way, how to convert 2:0 for example to 02:00 using RegEx ?

Thanks in advance

Answer 1

$hours = floor($seconds / 3600); $mins = floor(($seconds - ($hours*3600)) / 60;)

Answer 2

something like this?

 if(is_numeric($time)){
$value = array(
  "years" => 0, "days" => 0, "hours" => 0,
  "minutes" => 0, "seconds" => 0,
);
if($time >= 31556926){
  $value["years"] = floor($time/31556926);
  $time = ($time%31556926);
}
if($time >= 86400){
  $value["days"] = floor($time/86400);
  $time = ($time%86400);
}
if($time >= 3600){
  $value["hours"] = floor($time/3600);
  $time = ($time%3600);
}
if($time >= 60){
  $value["minutes"] = floor($time/60);
  $time = ($time%60);
}
$value["seconds"] = floor($time);
return (array) $value;

}else{ return (bool) FALSE; }

Answer 3

Use modulo:

$hours = $time_in_seconds / 3600;
$minutes = ($time_in_seconds / 60) % 60;

Answer 4

If the you know the times will be less than an hour, you could just use the date() or $date->format() functions.

$minsandsecs = date('i:s',$numberofsecs);

This works because the system epoch time begins at midnight (on 1 Jan 1970, but that's not important for you).

If it's an hour or more but less than a day, you could output it in hours:mins:secs format with `

$hoursminsandsecs = date('H:i:s',$numberofsecs);

For more than a day, you'll need to use modulus to calculate the number of days, as this is where the start date of the epoch would become relevant.

Hope that helps.

Answer 5

Let $time be the time as number of seconds.

$seconds = $time % 60;
$time = ($time - $seconds) / 60;
$minutes = $time % 60;
$hours = ($time - $minutes) / 60;

Now the hours, minutes and seconds are in $hours, $minutes and $seconds respectively.

Answer 6

Another solution that will give you the days, hours, minutes, and seconds for a passed-in seconds value:

function seconds_to_time($secs)
{
    $dt = new DateTime('@' . $secs, new DateTimeZone('UTC'));
    return array('days'    => $dt->format('z'),
                 'hours'   => $dt->format('G'),
                 'minutes' => $dt->format('i'),
                 'seconds' => $dt->format('s'));
}

print_r(seconds_to_time($seconds_value);

Extra logic will be needed for 'days' if the time is expected to be more than one year. Use str_pad() or ltrim() to add/remove leading zeros.
