如何使用PHP按照降序从日期中筛选表中的数据

Question

I need to fetch all data from table as per date field in descending order using PHP and Mysql. I am explaining my table below.

db_special:

id          name         date

1            Ram          12/04/2017 15:31:57 PM

2            Raj          12/03/2017 05:31:57 AM

3            Rahul        11/28/2017 12:30:54 PM

Here is my query:

select * 
from db_special 
where
    STR_TO_DATE(date, '%m/%d/%Y') 
    BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW()

Here I implemented one logic to fetch last 7 days data and now I need to implement sorting as per the same date field in descending order using MySQL and PHP .

Answer 1

Are you really using a VARCHAR/CHAR/CLOB field to store a date? That is very bad. It makes kittens cry. Please don't do it.

using PHP and Mysql

No. you don't retrieve data from a DBMS then sort it in PHP. That too is very bad (unless you're Facebook, in which case it is possibly a bit silly, but that is another story). You sort in the database.

Just add an ORDER BY clause at the end of your SELECT
