Witam,

zakladajac tablice:
$array=array("kot","pies","krowa","mysz","kot","pies","krowa","kot","pies","
krowa");

jak sprawdzic, nie tylko:
1. ile jest roznych elementow jak poprzez array_unique($array); (thnx pandp)
ale rowniez:
2. ile razy sie powtorzyly?

cos w rodzaju:
$tablica[kot]=3, $tablica[pies]=3, $tablica[krowa]=3, $tablica[mysz]=1.

zalezy mi na mozliwie najszybszym algorytmie - tablica ok. 5000 elementow do
porownania.

pozdrawiam,
Kamil
