older version of PHP

if the PHP version is older than 8.0, you need to add this line to the beginning of the php script ;-)
Otherwise export to csv doesnot working

if (!function_exists('str_starts_with')) {
    function str_starts_with(string $haystack, string $needle): bool {
        return substr($haystack, 0, strlen($needle)) === $needle;
    }
}
