            mysql_query("UPDATE package_transaction SET `status` = 'cancelled' WHERE `payment_due` = `$duedate` AND `transac_code` = `$transac_code`");

        }

    }
}

but its not working. please help

Answer 1

try this,

 date("Y-m-d", strtotime($date)) >  date("Y-m-d", strtotime($duedate))

Answer 2

could you try and use the date format before using strtotime

$duedate = $row['payment_due'];
$duedate = $duedate->format('Y-m-d G:i:s');
