如何使用 php 查找两个日期之间的天数

If I have two dates - how do I find the real difference in days between two dates? You must take things like leap years and the number of days in each month into account.

如果我有两个日期 - 我如何找到两个日期之间的实际天数差异？您必须考虑闰年和每个月的天数。

How many days are between something like 2010-03-29and 2009-07-16?

strtotimeand simple math:

strtotime和简单的数学：

   $daylen = 60*60*24;

   $date1 = '2010-03-29';
   $date2 = '2009-07-16';

   echo (strtotime($date1)-strtotime($date2))/$daylen;

check out PHP DateTimeclass. It deals with all the gory details so you can just do regular subtraction.

查看 PHP DateTime类。它处理所有血腥细节，因此您只需进行常规减法即可。

$d1=date_create('1999-10-23');
$d2=date_create('2004-04-17');

$i=date_diff($d2,$d1);
echo $i->format('%a');

Here you go:

干得好：

<?php
$date1 = strtotime("2010-03-29");
$date2 = strtotime("2009-07-16");
$dateDiff = $date1 - $date2;
$fullDays = floor($dateDiff/(60*60*24));
echo "Differernce is $fullDays days";
?>
