Is there a way in php to count how often a value exists in a large array?

So if I have an array like this:

$array = "1,2,3,4,joe,1,2,3,joe,joe,4,5,1,6,7,8,9,joe";

is there a way to output a new array that tells me (and sorts) which is used most and how many for each?

$result = array(
    [joe] => 4
    [1] => 3
    [2] =>2
    etc...
    )

I've seen the php array_count_values, but can this be sorted by most -> least? or is there an easier way?

Thanks everyone!

step 1, make it an array using the explode-function in PHP. – Simon André Forsberg Apr 5 '12 at 19:40

Sort them after counting them with arsort()

$result = array_count_values(explode(',', $array));
arsort($result);

Array
(
    [joe] => 4
    [1] => 3
    [2] => 2
    [4] => 2
    [3] => 2
    [9] => 1
    [8] => 1
    [5] => 1
    [6] => 1
    [7] => 1
)

and to make it sort in descending order, use the rsort function instead of ordinary sort. – Simon André Forsberg Apr 5 '12 at 19:40
@NullUserException Yes, I mixup arsort with krsort all the time. – Michael Berkowski Apr 5 '12 at 19:42
Thanks for your help! my code would have been much longer. I appreciate it! – iight Apr 5 '12 at 19:53
