    Here is a userland implementation that can be included in code that needs to support PHP 8.3 and below:

    <?php

    if (!function_exists('grapheme_str_split')) {
    function     grapheme_str_split(string $string, int $length = 1): array|false
    {
    if (    $length < 1) {
    throw new     \ValueError('Argument #2 ($length) must be greater than 0 and less than or equal to 1073741823');
    }

    try {
    return     preg_split('/(\X{' . $length . '})/u', $string, -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
    } catch (    \Throwable $e) {
    return     false;
    }
    }
    }

    ?>
