UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? PHP Variable Scope on Included Code

OK... We just upgraded to 7.7.0 and are reorganizing things to make management easier because we run 2 forums.

I didn't realize that code placed in these textboxes (screencap below) were within the smarty templates.

So, is it still OK to have PHP in the "Default Header" field? If so, that will still be useful.

Thanks for the help.
