Method Array.count()
- Method count
int count(array|mapping|multiset haystack, mixed needle)
mapping(mixed:int) count(array|mapping|multiset haystack)- Description
Returns the number of occurrences of needle in haystack. If the optional needle argument is omitted, count instead works similar to the unix command sort|uniq -c, returning a mapping with the number of occurrences of each element in haystack. For array or mapping haystacks, it's the values that are counted, for multisets the indices, as you'd expect.
