How do I get next month date from today's date and insert it in my database?

Question

I have two columns in my db: start_date and end_date, which are both DATE types. My code is updating the dates as follows:

Answer 1

01-Feb-2014

$date = mktime( 0, 0, 0, 2, 1, 2014 );

echo strftime( '%d %B %Y', strtotime( '+1 month', $date ) );
