 echo date('d/m/Y',strtotime('-1 Monday')); // 21/05/2018

The strtotime function accepts a string, in the format "US English date", and parse it into a timestamp , making it possible to add dates, get specific days, and count other features.

Examples:

Last Monday strtotime('-1 Monday');

Last Monday strtotime("last Monday");

Next fifth strtotime("next Thursday");

Next fifth strtotime("+1 Thursday");

Penultimate Monday strtotime('-2 Monday');

Next Monday strtotime('+1 Monday');

Catch the time now strtotime("now");

Using a textual date strtotime("10 September 2017");

Add a day strtotime("+1 day");

Add a week strtotime("+1 week");

Add a week, two days, four hours, and two seconds strtotime("+1 week 2 days 4 hours 2 seconds");

Pick today's date and add 10 days

$now = strtotime("now");

strtotime("+10 day",$now);
