php：无法在一年内增加两次（工作时间）

我必须在一年内增加工作时间。下面给出了如何增加工作时间

$time1 = 411:20 ;
$time2 = 107:15 ;

strotime（$time1）+strotime（$time2）//不起作用

$timestamp = strtotime($time1." +".$time2);
$endTime = date("H:i:s", $timestamp);
echo $endTime;

如何在时间方面添加它们我尝试了各种解决方案，但都不起作用

请帮助
这里有一个小的实用函数，用于计算您的时间：

它以
xx:xx:xx
格式返回

<?php
function add_time(array $times) {
    $seconds = 0;
    foreach ($times as $time)
    {
        list($hour,$minute,$second) = array_pad(explode(':', $time),3,null);
        $seconds += $hour*3600;
        $seconds += $minute*60;
        $seconds += $second;
    }
    $hours    = floor($seconds/3600);
    $seconds -= $hours*3600;
    $minutes  = floor($seconds/60);
    $seconds -= $minutes*60;

    return sprintf('%02d:%02d:%02d', $hours, $minutes, $seconds);
}


$time1 = "411:20";
$time2 = "107:10";

echo add_time(array($time1, $time2));

创建时间数组，即：

$timearray=array("411:20","107:15");
$tot=AddTime($time);
echo $tot;

AddTime函数如下所示：

public function AddTime($times) {
    $minutes=0;
// loop throught all the times
    foreach ($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);
}

您的输出将是：

518:35

试试这个解决方案

  $time1 = "411:20";
    $time2 = "107:15";

    $decimalHours = decimalHours($time1,$time2);

    function decimalHours($time1,$time2)
    {
        $hms = explode(":", $time1);
        $hms2 = explode(":", $time2);
      $t1 = ($hms[0] + ($hms[1]/60));
      $t2 = ($hms2[0] + ($hms2[1]/60));
        return ($t1 + $t2) ;
    }

echo $decimalHours;

您尝试过的“各种解决方案”是什么？请编辑您的帖子以添加它们。它也可以是000:00:00格式吗？很好，但我必须在foreach循环中使用它，它给出了错误致命错误：无法重新声明添加时间（）（之前声明的declareddeclare是for循环外的函数，仅在循环内使用函数_调用。请告诉我如何添加所有时间的完整总计，如559:00、574:15、508:10、554:45等等。可以将它们全部添加到
echo add_time（$array_variable_此处）
如果您的所有值都在数组中，是否有可能在foreach循环之外
  $time1 = "411:20";
    $time2 = "107:15";

    $decimalHours = decimalHours($time1,$time2);

    function decimalHours($time1,$time2)
    {
        $hms = explode(":", $time1);
        $hms2 = explode(":", $time2);
      $t1 = ($hms[0] + ($hms[1]/60));
      $t2 = ($hms2[0] + ($hms2[1]/60));
        return ($t1 + $t2) ;
    }

echo $decimalHours;
