如何在 HH:MM 格式的 php 中添加多个小时 - How to addition of multiple hour in php in HH:MM format

How to addition of multiple hour in php in HH:MM format

本文关键字：php 添加小时格式 HH MM | 更新日期: 2023-09-27

我有以下数组。

Array
(
    [0] => 25:50
    [1] => 21:00
    [2] => 42:40
)

我正在尝试在 php 中添加小时数，我已经尝试了以下代码。但它让我错误的时间计算。

$time_cal = 0;
foreach ($time as $time_cal) {
    $time_cal += strtotime($time_cal);
}
echo date('H:i', strtotime($time_cal));

这个strtotime函数背后的原因是只给出不到24小时的时间计算，这是正确的，但是当我尝试超过24小时（如25：55,44：44）时，给了我错误的计算。

任何想法？

这段代码可能对你很有帮助。我创建了两个函数1） explode_time2） second_to_hhmm

function explode_time($time) { //explode time and convert into seconds
        $time = explode(':', $time);
        $time = $time[0] * 3600 + $time[1] * 60;
        return $time;
}
function second_to_hhmm($time) { //convert seconds to hh:mm
        $hour = floor($time / 3600);
        $minute = strval(floor(($time % 3600) / 60));
        if ($minute == 0) {
            $minute = "00";
        } else {
            $minute = $minute;
        }
        $time = $hour . ":" . $minute;
        return $time;
}
$time = 0;
$time_arr =  array("23:59","01:01","2:50");
 foreach ($time_arr as $time_val) {
    $time +=explode_time($time_val); // this fucntion will convert all hh:mm to seconds
}
echo second_to_hhmm($time); // this function will  convert all seconds to HH:MM.

你可以使用它。

$remove_mins = date('H', strtotime( $time_to_add));
$time_cal = 0;
foreach ($time as $time_cal) {
    $time_cal = date('H:i', strtotime("+" . $remove_mins . " hour",strtotime( $time_cal)));
}
echo date('H:i', strtotime($time_cal));

当超过 24 小时时，如果您尝试添加分钟数，+hour 函数将不起作用，因此您只需要获取小时数而不需要分钟数

function AddTimeToStr($aElapsedTimes) {
  $totalHours = 0;
  $totalMinutes = 0;
  foreach($aElapsedTimes as $time) {
    $timeParts = explode(":", $time);
    $h = $timeParts[0];
    $m = $timeParts[1];
    $totalHours += $h;
    $totalMinutes += $m;
  }
  $additionalHours = floor($totalMinutes / 60);
  $minutes = $totalMinutes % 60;
  $hours = $totalHours + $additionalHours;
  $strMinutes = strval($minutes);
  if ($minutes < 10) {
      $strMinutes = "0" . $minutes;
  }
  $strHours = strval($hours);
  if ($hours < 10) {
      $strHours = "0" . $hours;
  }
  return($strHours . ":" . $strMinutes);
}
// your sample
echo AddTimeToStr(array("25:50", "21:00", "42:40")) . "<br/>";
// more flexibility. Lets you specify more than 99 hours
echo AddTimeToStr(array("100:50", "00:05", "22:40")) . "<br/>";
// check before, at, after hour boundaries
echo AddTimeToStr(array("00:50", "00:09")) . "<br/>";
echo AddTimeToStr(array("00:50", "00:10")) . "<br/>";
echo AddTimeToStr(array("00:50", "00:11")) . "<br/>";

要获取小时数：

substr($time_cal,0,2);

要获取会议记录：

substr($time_cal,3,2);

然后转换为数字，因为它是一个字符串

您可以使用

DateTime对象对日期进行操作

$dates = array("21:00", "01:05", "03:00");
$sum = new DateTime("00:00");
foreach($dates as $date)
{
    $elements = explode(':',$date);
    $hours = (string)((int)$elements[0]);
    $minutes = (string)((int)$elements[1]);
    $dv = new DateInterval('PT'.$hours.'H'.$minutes.'M');
    $sum->add($dv);
}
echo $sum->format('H:i');

这将输出01:05因为它会自动对小时进行取模。
