<?php
    function str_split_unicode(string $string, int $max_length = 200) : array
    {
        if ($max_length > 0) {
            $result = [];
            $char_length = mb_strlen($string, "UTF-8");

            for ($part = 0; $part < $char_length; $part += $max_length) {
                array_push($result, mb_substr($string, $part, $max_length, "UTF-8"));
            }

            return $result;
        }

        return preg_split("//u", $string, -1, PREG_SPLIT_NO_EMPTY);

The expression return preg_split('//u', $string, -1, PREG_SPLIT_NO_EMPTY) could return the type false which is incompatible with the type-hinted return array. Consider adding an additional type-check to rule them out.
