    It cannot be done directly but there is another way.!!

    Convert your date to unix timestamp using mktime(). It will only give a numerical value and substract it from current timestamp and it will give you the second difference.

$currtime = date('Y-m-d h:i:s');

$five_days_ago = strtotime($currtime." - 5 days"); // this is in timestamp format
$five_days_ago_date = date("Y-m-d h:i:s", $five_days_ago); // converted back to your date format

// another example
$one_month_later = strtotime($currtime." + 1 month");
$one_month_later_date = date("Y-m-d h:i:s", $one_month_later);
    PHP:
    In short,

    
$five_days_ago_timestamp = strtotime(date('Y-m-d h:i:s')." - 5 days");
