Date is important function in php.
This is a short guide on How to get last week date range monday to sunday in PHP. This is useful for whenever you need to figure out what date a particular date fell on (or will fall on in the future). In this tutorial, I will be retrieving the date from a YYYY-MM-DD string.
PHP Code
<?php
$previous_week = strtotime("-1 week +1 day");
$start_week = strtotime("last monday midnight",$previous_week);
$end_week = strtotime("next sunday",$start_week);
$start_week = date("Y-m-d",$start_week);
$end_week = date("Y-m-d",$end_week);
echo $start_week.'<br /> '.$end_week ;
?>
