Skrypt testuje na stronie http://ycd3.pl/gsm/

1.Jak zmienić datę,godzinę nagłówku z wiadomościami,na stronie pokazuje mi się wersja angielska a ja chciałbym aby wyświetlało się po polsku.
2.Jak zrobić aby po kliknięciu czytaj dalej nie przenosiło mnie na stronę z skąd pobrałem rss tylko na moją stronę i pokazywało ten sam tekst i pisało źródło tekstu.Kolega mi mówił że trzeba użyć read(); ale nie wie jak dokładnie to zrobić.Jak mam to zastosować na stronie?
3.Czy jest jakiś skrypt aby z pobieranych rss tworzyły się tagi? Jeśli nie to jak to stworzyć?

Nie mogę sobie poradzić z tymi 3 rzeczami,mam nadzieję że mi pomożecie

Pozdrawiam
