Because you've set $test equal to one element of $a (making it an
integer).  Array_unique() wants to operate on an entire array.

What I'd do, assuming I'm understanding the question correctly, would be
something more like:

        $a = range(0,9);

(That is, get all your values loaded first, then just randomly rearrange
the order.)
