Simple PHP MySQL Class
That’s right! I have a simple MySQL class file that you can use in your PHP projects. I’ve been using it for years, and it’s never let me down!
You can grab it on my Github: http://github.com/a1phanumeric/PHP-MySQL-Class.

JOIN (SELECT ROUND(
RAND( ) * (
SELECT MAX( id ) FROM )
) AS id
) AS r2
WHERE r1.id >= r2.id
ORDER BY r1.id ASC
LIMIT 1;
