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

If you want a specific date in next month, you can do this:

// Calculate the timestamp
$expire = strtotime('first day of +1 month');

// Format the timestamp as a string
echo date('m/d/Y', $expire);

Note that this actually works more reliably where +1 month can be confusing. For example...

Current Day   | first day of +1 month     | +1 month
