I'm told that I have to use the .shtml extension if I'm to have the server-side include in my index page execute, and I'm told that any PHP code must be in a page having the .php4 extension. But what if I want both?
Some in the Movable Type Support Forum have suggested that "There's some sort of declaration (similar to a script declaration for javascript)."
Does such a declaration exist? If not, can anyone advise further?
