Question

I have this urgent question about date in php. I want to query the database for certain records before a certain date, say I want records within 30 days, so first thing is I get current date, and I want to calculate the other end of the date range, how can I do that? Do I need to do this in mysql query or in php? Much appreciated!

Answer 1

You can easily do that in mysql.

eg.

SELECT * from myTable where date_column > date_sub(now(), interval 30 day);

now() or CURRENT_TIMESTAMP -> will give you a value of current date.
date_sub, and date_add are functions used to add or subtract interval
from given date.
