That's the ticket. The solution is pretty simple now that we
understand the nature of the problem. :-)

Andrew:

Half the solution is understanding the problem.

However, the above solution only solves half the problem.

Maybe I'm confused... but can't the following be used?


array_multisort( $votes, SORT_DESC, $items, SORT_DESC );
$final = array_combine( $items, $votes );

print_r( $final );

?>

Rob.

Rob:

You're never confused because you are always right.

Congrats, you were the first to solve this problem this simply.

To tell the truth, I didn't fully understand how array_multisort()
worked until I reviewed your solution. I thought array_multisort()
was to sort multi-dimensional arrays and simply overlooked the
description that it could also sort several arrays at once. Duh --
sometimes my reading/comprehension skills suck.

Many thanks for your time.

Cheers,

tedd
