Need some help regarding array sorting....

I have two arrays. The main one (where the key is the user id) :

$user[31] = 'Tom'

$user[43] = 'Jane'

and another array with the order they should be displayed (where key is the order and value is the user id) :

$order[1] = 43

$order[2] = 31

How can I apply the ordering to the main array using the ordering one?

Thanks guys!
