get_categories orderby random

[Ninos Ego]

There's no option to order the categories in the get_categories function by random..
Maybe you can include it in the next version.

get_posts etc. has got this option.

Unlike get_posts(), get_categories() doesn't have pagination, so you can just use shuffle():

$categories = get_categories();

shuffle( $categories );

Have used the shuffle function, but think, that my way brings a better performance..

Replying to Ninos Ego:

When you push randomization to SQL, it means we can't actually cache the results, as they're supposed to be random. get_posts() does pagination, which is why we push it to SQL — you need only X of Y posts, but a random X of them.

But get_terms(), as scribu said, isn't paginated. Thus, letting the query be cached, then shuffling them on your own, makes more sense.

ok thank you for the information..
