Did you take a wrong turn somewhere? This isn't a php forum, it's a perl forum.

use strict;
use warnings;
use 5.010;


my @numbers = (10, 20, 30);
say "The numbers are: @numbers";    #The numbers are: 10 20 30

my $aref = \@numbers;
say "The numbers are: @$aref";    #The numbers are: 10 20 30

say "One number is: @$aref[0]";   #10
say "Another number is: " . $aref->[2];   #30
