Function str_split Returns Empty Array for Empty String in PHP 8.2

PHP has a function str_split that can be used to convert a string to an array. In PHP versions before 8.2, the str_split function returns an array with a single empty string entry for empty string (str_split('') -> ['']). This behavior is unexpected and can cause issues.

Since PHP 8.2, the str_split returns an empty array for an empty string (str_split('') -> []).

<?php

var_dump(str_split('')); // array(0) {}
