Witam. Jestem w trakcie pisania pracy i większość strony robiona jest graficznie bez większej ingerencji w źródło, a że z PHP jestem od niedawna dlatego też nie znam jeszcze wszystkiego dokładnie. Jeśli ktoś ma chwilę czasu i chęci to proszę o ogólniejsze objaśnienie wierszy w podanym kodzie. Z góry bardzo dziękuję.
