Witam, napisałem swoją pierwszą klasę obsługi szablonów. Nigdy wcześniej tego typu klasy nie pisałem i prosiłbym o ewentualne wskazanie błędów lub co mógłbym zmienić/dodać/zrobić lepiej
Jak na razie wszystko działa - szablony się poprawnie kompilują i poprawnie są wyświetlane
Aktualnie zrobiona jest obsługa
{$zmienna},
{if $warunek}(...){elseif $warunek2}(...){else}(...){/if},
{foreach $instrukcja} (...) {/foreach}
oraz includowanie innych plików szablonu
