在不使用date_diff的情况下使用php减去日期以获得剩余天数

Question

I have two variables holding different dates in the database one is date created and the other is expiry date. How can I subtract the first date from the other so that I can return the remaining days using phpmysql.

Answer 1

I think your dates stores in datetime fields. So you can find diff in such way:

   $seconds = strtotime( $expired ) - strtotime( $created );
   /*** get the days ***/
   $days = intval($seconds / (60 * 60 *24));

Ofc, you can use DateTime for your purposes
