If you do: `@array1 = "foo bar baz";` [download] Then you have just one thing on the right hand side. Hence, you only get one thing on the left hand side, so `@array1` contains just one element. The `split` function, as documented in the manual page, takes a regex and a string as argument, and splits the string in several parts, based on the regex. An argument of `" "` is special, and splits the string on whitespace. Splitting `"foo bar baz"` on whitespace gives you a list of three strings, hence the array will contain three elements.
