Mapping an array to a string

[chuck_norris]

Hi guys, Is it possible to create a hash which maps an array to a string? If so, what is the syntax? Thanks, Chuck

What should that mapping looking like?

You can do something like

use Data::Dumper;
my $string = Dumper \@array;

Which represents an array as a string, but it doesn't use a hash (at least not visibly).

Could you rephrase your question, and provide one or two examples what the result should look like?

Hi chuck_norris

Did you want to do something like this

use strict;
my @AoH = (
{'Lead'=>'fred','Friend'=>'barney'},
{'Lead'=>'george','Wife'=> 'jane','Son'=>'elroy'}
);
my $string = \@AoH;
for my $href ( @$string) {   
     for my $role ( keys %$href ) {
         print "$role:$href->{$role}\n";
     }   
 }

If I understood correctly

use strict;
use warnings;

my @array=(1,2,3);
my %hash = ();

$hash{'string'} = \@array;

print $hash{'string'}[0];
print $hash{'string'}[1];
print $hash{'string'}[2];

Do you want to use arrays as hash keys? Only strings can be hash keys in Perl, but you can get a stringified representation of an array using eg. Data::Dumper or YAML, so you should do something like this:

use Data::Dumper;
$hash{Dumper(\@array)} = $value;
