i was going to say that PHP 7 wasn't that major from code golfing point of view, but then i realized it removed ereg and split functions
because changes like "you cannot name your classes int" are unimportant - you wouldn't call your classes int in code golf even if you could, when there are better names like A
or that exceptions don't have to be of Exception anymore which would affect set_exception_handler - unimportant for codegolf, no reason to use exception handlers for code golf
