如何在PHP中找到比另一个日期晚1天的日期？

Question

How can I find the next day's date after a given date.

For example, I have a date 2011-11-31 . How can I get the next date ( 2011-12-01 ) using PHP?

Similarly, how would I get the previous day's date?

Answer 1

$nextdate = date("Y-m-d",strtotime($olddate." +1 day"));

Answer 2

You can use the strtotime() function in php:

$date="2011-11-11";
$nextdate = date('Ym-d', strtotime($date . " +1 day"));
echo $nextdate;

It will echo as "2011-11-12".

Similarly to find the previous date use:
$nextdate = date('Ym-d', strtotime($date . " -1 day"));

It will echo as "2011-11-10".
