witam, nie znam sie na php a potrzebuję pomocy, strona którą mam ma w swoim kodzie taką funkcję (poniżej) - wyświetlającą jaki system i wersja. Obecnie serwer ma nową wersję php i wyświetlają sie błędy, ze eregi jest przestarzałe. Potrzebuję przerobienia z zamiast eregi na preg_match. czy ktoś może mi pomóc?
