Subject: Re: Ruby's equivalent of PHP explode

"Does it simply my_hash as an associative array?"
Hi
I think its better to call arrays arrays, and hashes hashes in Ruby.

I guess php simplifies this a bit too much for my taste,
with array() uniting both arrays and hashes.

Hash.new is the same as {} in ruby, although the second is a
tiny bit faster as far as I know.

nil means that something doesnt really exist, even an empty
'' string is not nil
