How to name an array with the name of the variable

[user2base]

I want to create an array whose name is the name of a scalar.
For instance, if I have:
$name = "arrayname";
I want to use $name to name my array rather than call it @arrayname.

It looks strange but it makes sense in my context as the value of the scalar $name will vary in a loop.

I have tried @\$name but it does not work.

Is it possible to do that ??

#!perl
$str = 'car';
@$str = ('vw','blue','GTI','hatch-back');

foreach (@car) { print "$_\n"; }

You may have to look into using

eval();

Create the string containing the PERL commands
you need and then

eval();

the string...

Sorry if my title was not descriptive enough.

Thanks for your answer but actually what I want to do is the opposite.

To simplify let's assume that for each key in a loop I want to create an array named "the value of that key".
The problem is that I don't have these values hardcoded like ('vw','blue','GTI','hatch-back') but there are dynamically created from a hash.

So I will have something like this:
for each $key (keys %hash)
push $key in an array called $hash {$key}

wow this is an old post, but I thought I should comment since I had the same problem/request.

goBoating had the right idea.

in my case, I have a number of data files that are the result of feedback forms. Each element of data is categorized, and I need to compile the results.
Instead of making 11ty billion arrays to collect the results for each field, and then list that many if statements (i.e. if line contains submittedBy { push @submittedBy, $data } ) - I wanted to automatically create the correct array and populate it (that way you don't actually need to know the data fields at all or how many).

goBoating's syntax worked well

I split the line using RE into $bin = field and $data = user input.
then "push @$bin,$data;"

this created and corectly populated all the arrays I needed.
