计算时差并将结果汇​​总到PHP中 [英] Calculate time difference and sum the results in PHP

问题描述

我有一个包含字符串形式的时间数据的数组，如下所示:

I have an array contains time data in string, like this:

$time = [
    "10:05:32",
    "11:03:43",
    "13:43:16",
    "10:17:21"
];

现在我要计算 $ time [x]-10:00:00 ，并对所有结果求和: 00:05:32 + 01:03:43 + 03:43:16 + 00:17:21 (= 5:09:52)

Now I want to calculate $time[x] - 10:00:00, and sum all the results: 00:05:32 + 01:03:43 + 03:43:16 + 00:17:21 (=5:09:52)

我已经在php.net中阅读了一些参考资料，但是所有内容都是关于日期的，没有简单的时间计算解决方案吗?

I have read some reference in php.net, but everything is about date, there is no a solution for simple time calculation?

推荐答案

我要做的是先将它们隐式标记为时间戳，然后映射差异，然后将其汇总.像这样:

What I would do is covert them to timestamp first, then map the differences then sum them up. Like this:

$diff = '10:00:00';
$time = ["10:05:32", "11:03:43", "13:43:16", "10:17:21"];
$time = array_map(function($t) use ($diff){
    return strtotime($t) - strtotime($diff);
}, $time);

$time = gmdate('H:i:s', array_sum($time));
echo $time; // 05:09:52
