I have a date variable stored in a MySQL database that is formatted as "2012-06-13." I want to use PHP to calculate three days into the future. I have tried experimenting with functions and formulas I found in the manual, but I seem to be missing something. They all break the code on my page.

Can someone please help me calculate the future date using these two variables?

$KWcurrentDate = "2012-6-13" ;
$KWdateDifference = "3" ;

(Not sure whether the quotes were neded or not, so I put them in.)

Any help would be appreciated.
