In a large bowl, combine the cream cheese, Parmesan cheese, mayonnaise, garlic, dried basil, garlic salt and pepper, and mix them well. Stir in the artichokes and spinach.
Preheat the oven to 350ºF. Transfer the dip mixture to a greased 9-inch pie plate. Sprinkle mozzarella cheese over the top. Bake, uncovered, for 20 to 25 minutes, or until the dip is bubbly and lightly browned at the edges. Serve with crackers, toasted bread or sliced vegetables.
