variable variable names?

[emilybartholomew]

Hi -

I searched around this forum & wasn't able to find what I was looking for. I am writing a script that loops through a variable number of Users who answer a survey & creates hashes for each of the Users that holds how they answered each question. I want to have hash names like %user1, %user2, etc., with the digit portion of the name variable. I tried things like
%user$UserID, %user'$UserID', %user.'$UserID'
but those didn't work. I feel like there's some easy answer to this I just can't put my finger on.

Thanks-
Emily

You could use something like:

${ "user" . $digit }{'Key'}= "Value";

to dynamically build the hash name. This will not work if you are using strict "refs". I would just build a multilevel hash with the user as the hash key and each user's survey as an anonymous hash. eg:

%survey = {
  'user1' => {
     'q1' => 'a1',
     'q2' => 'a2'
  },
  'user2' => {
     'q1' => 'a1-2',
     'q2' => 'a2-2'
  },
  ...
}

Hope that helps.
