PHP

php. There is a large array that I got by splitting a long string into words. Now you need to display the 20 most popular words that are most often found in the same array (string).
How to do it?

<?php
$array = array(1, "hello", 1, "world", "hello");
$counter = array_count_values($array);
arsort($counter);

print_r(array_slice($counter,0,20));
?>

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