Date Manipulation in PHP, MySQL, ADDT

Question

I have a datetime stored in MySQL  I retrieve it from the ADDT update transaction via the following statement:
$last_date = KT_escapeForSql($tNG->getColumnValue("last_kpi_gen_date"),$tNG->getColumnType("last_kpi_g en_date"));
Now I want to add 1 day, 7 days, or a month to the date.  I try using mktime but it appears it wants it in a different date order (h,m,s, y-m-d),  I've tried the strtotime function and the date function to reformat $last_date, but it doesn't seem to work.
Is there an easy way to add days to a date varible extracted from a MySQL database using ADDT getColumnValue?

Hi, I am trying to do it this way:
You can make VIEW for MySQL with current time +8 hours:
create view DATETIME as
SELECT DATE_FORMAT(DATE_ADD(now(), INTERVAL 8 HOUR), '%Y-%m-%d %H:%i:%s') as DT_add8hour;
Or with +8 days:
create view DATETIME as
SELECT DATE_FORMAT(DATE_ADD(now(), INTERVAL 8 DAY), '%Y-%m-%d %H:%i:%s') as DT_add8day;
This stores allways CURRENT time plus interval value. So You can use this to update other table colums to time you want. Works perfectly with DW+ADDT+PHP+MySQL  
Here are more Date and Time Functions
Hope this helps you!
