I'm trying to add months to a date using the following function

 date('Y-m-d', strtotime("+238 months", strtotime("2018-02-25"))) // gives the correct date as 2037-12-25

The function works when the I'm trying to add less than 238 months. When I tried to add a bigger number it gives the wrong answer as 1969-12-31.

 date('Y-m-d', strtotime("+239 months", strtotime("2018-02-25"))) // gives the wrong date as 1969-12-31.

If this is not the correct way to do, please suggest a function that works for the bigger months. Thank you.

It's the year 2038 bug – John Conde Feb 26 '18 at 02:41
is there a way to fix it? – Julia Feb 26 '18 at 02:42
Yes. Use PHP's DateTime objects, or better yet, [the Carbon library](http://carbon.nesbot.com/docs/). In Carbon, it'd be `Carbon::now()->addMonths(239)`. – ceejayoz Feb 26 '18 at 02:43
DateTime works well $date->modify('+239 month'), thank you. – Julia Feb 26 '18 at 02:49
@Julia - Indeed Carbon is simply a extension of DateTime, I've looked at the source code for it. So why use the extension for something so simple? – ArtisticPhoenix Feb 26 '18 at 03:37
I didn't use the Carbon library, I just used the built in DateTime. – Julia Feb 26 '18 at 15:12
