問題描述

我正在使用以下示例代碼來計算兩個不同時間值的總和.現在我想得到 N 個時間值的總和.

I am using the following sample code to calculate sum of two different time values. Now I want to get the sum of N number of time values.

// numbers for testing
$o="12:59";
$p="0:58";

// display for testing
echo "$o<br />";
echo "$p<br />";
echo AddPlayTime($o,$p);

// FUNCTION - ADD HOURS and MINUTES
function AddPlayTime ($oldPlayTime, $PlayTimeToAdd) {
  $old=explode(":",$oldPlayTime);
  $play=explode(":",$PlayTimeToAdd);

  $hours=$old[0]+$play[0];
  $minutes=$old[1]+$play[1];

  if($minutes > 59){
    $minutes=$minutes-60;
    $hours++;
  }

  if($minutes < 10){
    $minutes = "0".$minutes;
  }

  if($minutes == 0){
    $minutes = "00";
  }

  $sum=$hours.":".$minutes;
  return $sum;
}

推薦答案

這應該滿足您的要求:

$times 是時間數組，你可以添加你想要的時間

$times is the array of times and you can add how many time you want

$times = array();

$times[] = "12:59";
$times[] = "0:58";
$times[] = "0:02";

// pass the array to the function
echo AddPlayTime($times);

function AddPlayTime($times) {
    $minutes = 0; //declare minutes either it gives Notice: Undefined variable
    // loop throught all the times
    foreach ($times as $time) {
        list($hour, $minute) = explode(':', $time);
        $minutes += $hour * 60;
        $minutes += $minute;
    }

    $hours = floor($minutes / 60);
    $minutes -= $hours * 60;

    // returns the time already formatted
    return sprintf('%02d:%02d', $hours, $minutes);
}

編輯

我用正確的變量名稱編輯了代碼.現在更正確了.

I edited the code with the right names of the variables. It is more correct now.

希望這有幫助:-)
