Getting day before on a set date (not todays date)

[dc_jt]

Hi

 

I have a date which is set as 2007-02-01, can easily be changed to different format.

 

However how do I change this date to the day before?

 

In this case 2007-01-31?

 

Thanks

You can use the strtotime() function:

<?php
$date = '2007-02-01';
$day_before = date('Y-m-d',strtotime($date . ' -1 day'));
echo $day_before;
?>

Or you can get the UNIX timestamp of the date and subtract 86,400 (the number of seconds in a day) from it:

<?php
$date = '2007-02-01';
$day_before = date('Y-m-d',strtotime($date) - 86400);
echo $day_before;
?>
