Ok, I seen loooodes of threads on this elsewhere but no proper answer:

In a MySQL table there is a date in the format of yyyy-mm-dd. I want to add 30 days onto that. It qould probably be done by PHP, or my a MySQL table. But remember you must take into account the amount of days in each month etc. Its a hard problem to solve and as far as I've seen PHP or SQL dosn't have any functions to do it directly. Has anyone got any help at all?
