PHP date and time application 10: Convert seconds into the format 'day, hour, minute and second'

In the previous article "PHP date and time application nine: Get the start and end dates of a certain week in a certain year", I introduced you how to get the start and end dates of a certain week in a certain year. This article continues Let me introduce to you how to convert a number of seconds into a specific format of days, hours, minutes and seconds.

For example, how to convert 200000 seconds into a specific format of days, hours, minutes and seconds?

Do you have any ideas for implementation?

The following is an implementation method I gave for your reference:

The PHP code is as follows:

<?php

function convert_seconds($seconds)
{
    $dt1 = new DateTime("@0");
    $dt2 = new DateTime("@$seconds");
    return $dt1->diff($dt2)->format(&#39;%a 天, %h 时, %i 分 %s 秒&#39;);
}
echo convert_seconds(200000)."<br>";

The output result is:

There is a class that everyone needs to understand here, which is the DateTime class. (Recommended article: "How to use the datetime class in php? Introduction to the usage of datetime in php")

DateTime update log is as follows:

PHP7.2.0版本：DateTime 的类常量现在定义在 DateTimeInterface 上。
PHP7.0.0版本：新增常量：DATE_RFC3339_EXTENDED 和 DateTime::RFC3339_EXTENDED。
PHP5.5.0版本：实现 DateTimeInterface 接口。
PHP5.4.24版本：COOKIE 格式从 2 位数字表示年份（RFC 850） 修改为 4 位数字表示年份（RFC 1036）。
PHP5.2.2版本：DateTime 对象进行比较操作（comparison operators）的时候 可以正常工作了。 在之前的版本中，当使用 == 进行相等比较的时候， 所有的 DateTime 对象都会被视为是相等的。
