How do I find most used 10 words in php

<?php $arr = ['a', 'b', 'a', 'c', 'd', 'd', 'd']; /* Or this, if your input is a string $arr = explode(' ', 'a b a c d d d'); */ $arr_count = []; foreach ($arr as $v) { $arr_count[$v] = isset($arr_count[$v]) ? $arr_count[$v] + 1 : 1; } arsort($arr_count); print_r($arr_count);
