How to calculate the difference between two dates using PHP?
Date Difference in php?
I have two dates in a variable like
$fdate = "2011-09-01"
$ldate = "2012-06-06"
Now I need the difference in months between them.
For example, the answer should be 10 if you calculate this from month 09 (September) to 06 (June) of next year - you'll get 10 as result.
How can I do this in PHP?
回答1:
A more elegant solution is to use DateTime and DateInterval.
<?php
// @link http://www.php.net/manual/en/class.datetime.php
$d1 = new DateTime('2011-09-01');
$d2 = new DateTime('2012-06-06');
// @link http://www.php.net/manual/en/class.dateinterval.php
$interval = $d2->diff($d1);
$interval->format('%m months');
回答2:
Have a look at date_diff:
<?php
$datetime1 = date_create('2009-10-11');
$datetime2 = date_create('2009-10-13');
$interval = date_diff($datetime1, $datetime2);
echo $interval->format('%m months');
?>
