I was looking at this post, and it is close to what I need: http://stackoverflow.com/questions/1669165/php-how-to-count-60-days-from-the-add-date

However, in that post, the calculation is performed by adding 60 days to the current date. What I need to do is calculate the date based on a variable date (and not the current date).

Something like this:

$my_date = $some_row_from_a_database;
$date_plus_10_days = ???;

Anyone know how to do that?

Thanks
