How can I call a PHP function inside a hardcoded shortcode?

Question

Maybe I'm doing this the long way but I need to make something like this:

<?php echo do_shortcode('[mu-events months="11" startmonth="today" orderby="time" orderas="ASC" sites="?> <?php get_current_site();?> <?php"]'); ?>
<?php echo do_shortcode('[mu-events months="11" startmonth="today" orderby="time" orderas="ASC" sites="11"]'); ?>

I guess I simply don't know if a function can be inserted inside a shortcode, but in this case it seems like it just has the incorrect syntax.

Appreciate any pointing in the right direction!
Thanks

NOTE There is a different between CURRENT_SITE and current BLOG_ID, see my note below

You could do it in this way.

echo do_shortcode('[mu-events months="11" startmonth="today" orderby="time" orderas="ASC" sites="' . get_current_site() . '"]');
