In PHP, how do I chunk strings with strong typing?

In PHP, you can create a function that uses strong typing to chunk strings. Below is an example of how to do this:


        <?php
        function chunkString(string $string, int $chunkSize): array {
            $chunks = [];
            for ($i = 0; $i < strlen($string); $i += $chunkSize) {
                $chunks[] = substr($string, $i, $chunkSize);
            }
            return $chunks;
        }
        
        // Example usage
        $result = chunkString("HelloWorldThisIsAnExample", 5);
        print_r($result);
        ?>
