Week before date

[dc_jt]

Im looking to get the date 7 days ago.

 

I know how to do 7 days ahead:

 

$timeStamp = strtotime($oLastBatchDate->Last);

$timeStamp += 24 * 60 * 60 * 7;

$NextBatchDate = date("Y-m-d  H:i:s", $timeStamp);

 

However, does anyone know how to do 7 days back?

 

Thanks

echo date("Y-m-d", mktime(0, 0, 0, date("m"), date("d") - 7, date("Y")));

Check out strtotime() in more detail:

<?php
$timeStamp = strtotime("{$oLastBatchDate->Last} +7 day"); // 7 days ahead
$timeStamp = strtotime("{$oLastBatchDate->Last} -7 day"); // 7 days behind
?>

I know it would get the same result, but +/-1 week in strtotime would to it as well. strtotime can translate (almost) any formatted date into a timestamp and calculate relative to "now" or a specified date or timestamp.
