You can, and its probably best to use:

fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;


Also you should have those to in different nginx config files, its far
better to read/modify if needed.
In any case the .php block should work has long has the "root" is set
right in the different locations!
