我如何在PHP中计算2个变量日期之间的天数 - How can I calculate the number of days between 2 variable dates in PHP?

How can I calculate the number of days between 2 variable dates in PHP?

本文关键字：日期变量之间 2个计算 PHP | 更新日期: 2023-09-27

我在网上搜索了一下，但没有看到太多的帮助。

是否有一个准备使用函数来做到这一点在PHP，我还没有发现?

我想计算两个可变日期之间的天数，例如:

$date1 = '01/08/2014'; $date2 = '07/08/2014;

我尝试了以下，但$count是空的:

<?php
$date1 = '01/01/14';
$date2 = '07/01/14';
$count = $date1->diff($date2);
echo $count;
?>

$from = DateTime::createFromFormat("d/m/Y",$date1);
$to = DateTime::createFromFormat("d/m/Y",$date2);
$diff = $from->diff($to,true);
$days = $diff->days;

 $now = time(); // or your date as well
 $your_date = strtotime("2010-01-01");
 $datediff = $now - $your_date;
 echo floor($datediff/(60*60*24));

或者你甚至可以像这样使用PHP的date_diff函数:

$interval = $date1->diff($date2);

http://php.net/manual/en/datetime.diff.php

使用DateTime::diff(又名date_diff):

$datetime1 = new DateTime('2009-10-11');
$datetime2 = new DateTime('2009-10-13');
$interval = $datetime1->diff($datetime2);
Or:
$datetime1 = date_create('2009-10-11');
$datetime2 = date_create('2009-10-13');
$interval = date_diff($datetime1, $datetime2);

你可以通过调用$interval->days来获得一个整数形式的间隔。
