Php 计算总小时数

在php中，给定字符串格式的时间，如何添加超过24小时的小时、分钟和秒？ 前

结果是：

---

“34:00:15”

您将无法使用典型的日期类（如

DateTime

）或函数（如

date（）

）来输出超过24小时的时间。因此，您必须手动执行此操作

首先，您需要将时间设置为秒，以便轻松地将它们相加。您可以使用

explode

功能获取小时、分钟和秒数，并将这些值乘以所需秒数。（60秒等于1分钟。60*60秒等于1小时）

然后需要输出小时、分钟和秒的总数。这可以通过除法（同样，1小时是60*60秒，因此将秒数除以60*60得到小时）和模数运算符（

%

）得到分和秒的“余数”，非常容易实现

<?php
// Starting values
$time1 = "10:50:00";
$time2 = "24:00:15";

// First, get the times into seconds
$time1 = explode(":", $time1);
$time1 = $time1[0] * (60*60)    // Hours to seconds
            + $time1[1] * (60)  // Minutes to seconds
            + $time1[2];        // Seconds

$time2 = explode(":", $time2);
$time2 = $time2[0] * (60*60)    // Hours to seconds
            + $time2[1] * (60)  // Minutes to seconds
            + $time2[2];        // Seconds

// Add the seconds together to get the total number of seconds
$total_time = $time1 + $time2;

// Now the "tricky" part: Output it in the hh:mm:ss format.
// Use modulo to determine the hours, minutes, and seconds.
// Don't forget to round when dividing.
print 
    //Hours
    floor($total_time / (60 * 60)) .
    // Minutes
    ":" . floor(($total_time % (60 * 60)) / 60) .
    // Seconds
    ":" . $total_time % 60;

    // The output is "34:50:15"
?>

那么，您预期的结果是什么？您尝试了什么？我尝试提取小时、分钟和秒，并将其存储在一个变量中，然后手动添加它们。比如秒数>60加1分钟..效果很好，先生！！我将尝试分析它是如何完成的，也许我可以用DateTime重写你的答案：）谢谢！

            + $time1[1] * (60)  // Minutes to seconds
            + $time1[2];        // Seconds

$time2 = explode(":", $time2);
$time2 = $time2[0] * (60*60)    // Hours to seconds

    // The output is "34:50:15"
?>

print 
    //Hours
    floor($total_time / (60 * 60)) .
    // Minutes
    ":" . date('i', $total_time) .
    // Seconds
    ":" . date('s', $total_time);
