PHP + MySQL-随机列出MySQL表中的所有数据

Question

I got a table named clients in MySql. I want to list all the data from that table randomly in a php webpage. Is it possible to random the data whenever user visit the php webpage?

Thank you :D

Answer 1

You could do it like this:

SELECT * FROM mytable ORDER BY RAND();

This is mentioned in an example here . As mentioned in the documentation , rand() doesn't generate perfectly random numbers/sequence (but it will probably suffice for practical use on a website).

You could also use limit to select only N (eg 5) records:

SELECT * FROM mytable ORDER BY RAND() LIMIT 5;

Answer 2

Add an ORDER BY RAND() clause to your query.

One warning though, this sorting will not be very efficient...

Answer 3

SELECT * FROM clients
ORDER BY RAND()
