Question

I have a question on calculating times.

I have a simple table filled with 3 columns. column 1 will be passed by NOW() in the VALUE. The second column should be the NOW() timestamp plus 14 days. I never used timefunctions before, so I do have some understanding problems.

So is it possible when I have:

$copy = "INSERT INTO table (a, b, c) VALUES (NOW(), $var_for_b, $var_for_c)";

to use for

$var_for_b 

easily

NOW()+14d

or do I have to set a variable with a time/date function?

in case of using a variable what can I do there?

$in_14_days =mktime(+14d)

and my third column should simply be the difference between the NOW() and the NOW(+14d).

I’m sorry for this question but there are so many timefunctions that I do not guess the differences between them.

Answer 1

You can do now() + interval 14 day to set a date in the future.

so your insert statement becomes:

$copy = "INSERT INTO table (a, b, c) VALUES (NOW(),now() + interval 14 day, $var_for_c)";
