试图在 PHP 中定义我自己的时间类型 [英] Trying to define my own time type in PHP

问题描述

所以我试图定义一个时间类型，但我不太确定如何去做.我在网上找到的答案给出了用当前时间定义时间类型的例子(即 date("h:i:sa"))但是我正在尝试定义一个硬编码版本.我的格式想要的是 (HH:mm:ss) (hour:minutes:seconds) 我需要将变量声明为时间类型的原因是为了以后可以使用它们进行比较.

So I am trying to define a time type and I am not quite sure how to do it. The answers I find online give examples of defining a time type with the current time (i.e date("h:i:sa")) however I am trying to define a hard coded version.The format I want is (HH:mm:ss) (hour:minutes:seconds) The reason why I need the variable to be declared as time type is so that they can be used later on to be compared.

<?php 
$my_time = '10:00:00';
$your_time = '11:00:00';
if($my_time > $your_time){
echo "You have less time";
}
?>

推荐答案

PHP DateTime 类就是你所需要的.

The PHP DateTime Class is what you need.

//instantiate a DateTime Object      
$time = new DateTime();

//Use the DateTime obj to create two new DateTime objects
$yourTime = $time->createFromFormat('h:i:s', '12:30:30'); //third param here can define tz
$theirTime = $time->createFromFormat('h:i:s', '12:10:15');

//Use diff() to return a DateInterval
$dateInterval = $yourTime->diff($theirTime);

//Format the DateInterval as a string
$differenceBetweenYoursAndTheirs = $dateInterval->format('%h:%i:%s');

//Do something with your interval
echo "The difference between {$yourTime->format('h:i:s')} and {$theirTime->format('h:i:s')} is $differenceBetweenYoursAndTheirs";
