# Mutlisite and functions.php – How this works

 * Hey all.
 * For some reason I am unable to find any information on this.
 * If you are using the same theme throughout a few WP sites running multisites,
   is there a way to have different functions.php files for each site? If so, where
   does it live? and can I have a global file as well as individual files?
 * My reasoning is that I have some global settings that I want throughout my sites(
   security stuff) but each site will have a few different custom post types that
   need to be declared.
 * Thanks for any and all help.

 * > is there a way to have different functions.php files for each site
 * funtions.php is done by theme, not site.
 * That said, you could code into your functions.php a check for WHICH site is running,
   and then call it like this:
 * `include("http://yoursite.com/path/to/site-functions.php");`
 * Or maybe
    `include("http://yoursite.com/path/to/site-#-functions.php");`
 * You’ll have to play around.
