PHP makes a ranking, according to the time rank
PHP to do a ranking, according to the time ranking, the chart is in reverse chronological order, queued fields need to be ordered by time.

The correct queuing sequence and sequence number are reversed 5.4.3.2.1
------Solution--------------------
Not order by time, okay?
------Solution--------------------
If you sort by ID, you can write this

SELECT * FROM table order by id desc;

------Solution--------------------
Your queue column has no data.
------Solution--------------------
ORDER BY Field
DESC or ASC

Ascending desc
Descending ASC
------Solution--------------------
Your serial number is generated when the PHP code is output.
So your ranking is the total number-serial number

Ordinal rank
1     5
2     4
3     3
4     
5     1
