Zaranee izvenite za translit :)
Funkzia dlia podscheta kol-va vetok v dereve beret uinu vremeni, kogda mnogo vetok.
DB (ia uprostil) sdelana tak: ID / login / ref
id + login - dannogo pol'zovatelia
ref - pod kem etot pol'zovatel' nahoditsia, esli ne pod kem to ref=0.
funkzia sobstvenoo:
Kakie misli po optimizatsii?
Vozmozhno stoit dobavit' prosto v DB peremennuu total_members i sohraniat' tam kol-vo pol'zovatelei v dereve?
