Try simply using array_map,count,& array_unique like as

array_map(function($v) {
            return count(array_unique($v));
        }, $arr);

You cannot get a more elegant solution.

Use array_unique() and then count.

count(array_unique($array['Cop']));// output 2

If you want to print for every key do following:

$array = array('Cop'=>array('Dozen','Dozen','Akls','Akls'), 'MSN'=> array('Dozen'), 'NeK'=> array('Suhan','Ebao'));
foreach($array as $key => &$value) {
    $value = count(array_unique($array[$key]));
}
print_r($array);

Output:

Cop = 2
MSN = 1
NeK = 2

You should use array_count_values() for that, here's an example:

$data = array('cop' => array(0 => 'test', 1 => 'test', 2 => 'test2'));

foreach($data as $item){
    $result = array_count_values($item);
    print_r($result);
}

Outputs:

Array
(
    [test] => 2
    [test2] => 1
)
