Perhaps you want: 
@array = split ' ', $input{'dummy_a'};

    it worked.. why do i have to include this statement --split ' ', ---what does this do. 
    @array1 = split ' ', $input{'dummy_a'};

$array_lenth = @array = (@array1);

      If you do: 
          @array1 = "foo bar baz";

      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.
