Question

I need to calculate an end date based on todays date and a number of months. For example, todays date 04/01/2010 and the number of months is 6. Are there any functions I can use to do some math that would return “10/01/2010”?

Also, I think it’s important to note that I am storing the result in MySQL as a “DATETIME” so I guess I would have to do something with the time as well… ???

Thanks!

If you are storing the result as a DATETIME in MySQL, then the following code is probably what you want:

$mysqlDate = date("Y-m-d H:i:s",strtotime("+6 months"));

strtotime() turns a string into a timestamp, and will work from the current time with a relative value by default. date() will use that timestamp, and the format string above will give you a MySQL-friendly TIMESTAMP value.

e.g.:

echo date("Y-m-d H:i:s",strtotime("+6 months"));
//outputs 2010-10-01 11:19:17
