php - 如何将整数转换为日期时间？

Question

我有一个平均时间的数字。我想返回时间格式，如“00:00:12”我该怎么做？

a_function(){

  $sum_duration = Model::where('as_user_id',$this->id)->sum('duration');
  //sum_duration = 21
  $week_count = $first_impression->created_at->diffInWeeks($last_impression->created_at);
  //week_count = 2

  $time = date_create(round($sum_duration / ($week_count == 0? 1:$week_count)));
  //false

  return date_format( $time,"H:i:s");
}

上面的代码不起作用。我如何更改以显示时间格式，如 00:00:00 ((H:i:s))

Answer 1

我假设你有Carbon；

$sum_duration = 21; // from your calculation
$week_count = 2; // from your calculation
$default = Carbon::now()->setTime(0, 0); // set as 00:00:00
$difference = round($sum_duration / ($week_count == 0 ? 1 : $week_count)); // your calculation
$default->addSeconds($difference); // add seconds to 00:00:00

return $default->format('H:i:s');

编辑了秒
