A small issue with finding time difference between 2 dates and then combining the difference with new time.

[imgrooot]

// find the time difference between now and the expiry date

$expiry_date      = '2017-04-20 09:02:23';

$then             = new DateTime($expiry_date);

$now              = new DateTime();

$remaining_time   = $then->diff($now);


// I want to add two weeks to the new date.

$two_weeks        = $now->add(new DateInterval('P2W'))->format('Y-m-d H:i:s');


// new date that combines the remaining time from above and adds 2 weeks to create a new date. This is the issue here. How do I combine these two dates properly? The new date has to be in this format ('Y-m-d H:i:s')

$new_date         = $remaining_time + $two_weeks;

You want now + difference between now and then + two weeks? Isn't that the same as then + two weeks?

You want now + difference between now and then + two weeks? Isn't that the same as then + two weeks?

 

Now that I think about it, I guess your right.

 

Anyways I have solved the issue already. Here it is.

// find the time difference between now and the expiry date
      $expiry_date      = '2017-04-20 09:02:23';
      $then             = new DateTime($expiry_date);
      $now              = new DateTime();
      $remaining_days   = $then->diff($now)->format("%a");
      
      // I want to add two weeks to the new date.
      $current          = new DateTime();
      $two_weeks        = new DateInterval('P2W');
      $total_date       = $current->add($two_weeks)->format('Y-m-d H:i:s');

      // current date + 2 weeks + remaining days difference
      $dateTime = new DateTime($total_date);
      $new_date = $dateTime->modify('+'.$remaining_days.' days');


      echo $new_date->format('Y-m-d H:i:s');
