How to get the Unix Timestamp for one month in the future given a date

Question

Suppose I pull a field from the database, a timestamp field.

How do I get the Unix Timestamp, 1 month in the future, from that timestamp field?

My brain is a bit tired, so I need a bit of a re-jogging.

Answer 1

$newDate = strtotime('+1 month',$startDate); 

Using strtotime() you can pass it '+1 month' to add a context sensitive month.

Answer 2

I would use the strtotime() function, to add +1 month to your timestamp :

$future = strtotime('+1 month', $current_time);

With strtotime(), you don't have to think yourself about stuff like "some month avec 30 days, and others have 31", or "february sometimes has 28 days and sometimes 29".

After all, adding one month to a date is a bit harder that adding 30*24*3600 seconds...

You could also work with the DateTime class, and methods such as DateTime::modify() or DateTime::add().
