In PHP, how do I chunk strings in Symfony?

In Symfony, you can chunk a string using PHP's native functions. A common approach is to use `mb_substr()` to ensure that you're dealing with multibyte characters correctly. Here's an example of how you can implement string chunking in a Symfony controller:


        <?php
        // Example of chunking a string in Symfony
        function chunkString($string, $length) {
            return mb_split("(?<=\G.{{$length}})", $string); // Splits the string into chunks of specified length
        }
        
        $string = "Hello Symfony! This is an example of string chunking.";
        $chunks = chunkString($string, 10);
        foreach ($chunks as $chunk) {
            echo $chunk . "<br>";
        }
        ?>
