How can I change the following SQL statement to this format?

How can I change the following SQL statement to this format?

Read random rand function statements
This is generally the case.
SELECT *
FROM 'table'
WHERE id> = (select floor (MAX (id) * RAND () FROM 'product ')
Order by 'product _ id desc ';

The source code I downloaded should be in the function format! I don't know how to change it.
$ Product_tuijian = $ db-> pe_selectall ('product', array ('product _ istuijian '=> 1, 'product _ state' => 1, 'order by' => 'product _ id desc '),' * ', array (5 ));

How can I change the preceding statement into the following statement?

Cool! Which source code is displayed! I have been searching for this source code function for a long time, but it is not that complicated. Modify it.
