[php] Concurs 2 : date calendaristice

Concursul 1, a lamurit (sper) ce inseamna formular, si cum se pot prelua variabilele introduse in el.
Acum sa trecem la cautare functii pe site-ul PHP:
http://www.php.net/time

Sa se creeze un formular in care se cere anul, luna, ziua, ora, si minutul zilei de nastere.
Se cere sa se afiseze virsta.

Concursul dureaza pina pe 15 iulie, postati solutiile, dar sursele mi le timiteti sa zicem pe 14.

Daca e prea greu pentru incepatori, se cere doar anul in formular.

Re: [php] Concurs 2 : date calendaristice

Mai sunt citeva zile pina la expirarea concursului.

Vreti sugestii ? :
In lipsa unor functii deja facute, cum scadeti lucruri care nu sunt in baza 10 ?
Secundele se numara de la 0 pina la 59, si apoi se numara un minut, dar asta e la adunare asa ?
Daca vrei sa scazi din 20 de minute si 0 secunde, 40 de secunde ?
Pai din 0 secunde nu ai cum, scrii 19 minute si 20 de secunde.
