array_count_values randomise matching values

Question

I know the below code

<?php
    $array = array("1", "hello", "1", "world", "hello");    
    print_r(array_count_values($array));
?>

Will output:

Array
(
    [1] => 2
    [hello] => 2
    [world] => 1
)

I would like to retrieve the value which has been repeated the most, or if there are multiple matching instances which have been repeated the most e.g "hello" and "1" randomise them instead of retrieving the first one.

$array = array(1, "hello", 1, "world", "hello",'2','2','2','3','3','3');

$s = array_count_values($array);
$mostRepeated = max($s);

$s = array_filter( $s, function($v) use ($mostRepeated) {
  return $v==$mostRepeated;
});

print_r($s);    
echo array_rand($s);  // randomized

Step:

find the highest count
remove elements with less frequency
return an element random with array_rand

Note that I wrote this function to be transparent whenever there are a single or multiple entries with the same value count.
