Sorting and Limiting Results

I haven't been able to get this one to work properly. Basically someone takes a test. Each question has 5 possible answers and is given a value of 1-5. Then the results are added up like so:
Q1+Q37+Q73 = $somevar so if someone chose Very Much (value of 5) for all 3 questions, $somevar = 5+5+5 = 15
There are 18 different categories that need to be added up like this. Once this categories are all added up, they are added to an associative array and given key/values. Something like:

$array = ("key1"=>$somevar,
"key2"=>$somevar2,
etc. on up to 18);

That array is then sorted in reverse order with the top score at the beginning. That works fine.

arsort($array);

What I am having problems with is how to limit the results to the top 5 categories. Any ideas on this one?

You just want the top 5 elements of the associative array?

<?php
$top5 = array_slice($array, 0, 5);
?>

You know I knew that it wasn't something easy but I couldn't seem to come up with it. Thanks, bud.
