计算两个时间戳之间的总小时数 [英] Calculate total hours between 2 time stamps

问题描述

我有两个变量：

I have two variables:

$start_time = '9:36';
$end_time = '12:47';

我如何计算两次之间的小时数并将它们存储在如下变量中：

How would i calculate the amount of hours between the two times and store them in a variable like this:

$total_hours = 3;

我读过，您需要先转换时间。

I have read that you need to convert the times first. Also there will be no need for date as this will all be on the same day.

任何帮助将不胜感激

推荐答案

这解决了您的问题：

This solves your problem:

$start = explode(':', $start_time);
$end = explode(':', $end_time);
$total_hours = $end[0] - $start[0] - ($end[1] < $start[1]);

请参阅此键盘作为证明。

此解决方案假定两个小时都是同一天。

This solution assumes both hours are from the same day.
