how do I access this item?

I am using Data::Dumper. My code is:

use Data::Dumper;
blah, blah, blah.....
print Dumper \@data;

My output is:

$VAR1 = [
      [
        'Dave',
        'Green',
        '5',
      ],
      [
        'Bob',
        'Yellow',
        '4',
      ]
    ];

How do I access 'Bob' or '5'? Also, how can I turn @data into a hash or variable in order to put the enti开发者_JAVA技巧re contents into a database?

EDIT: @data is created from reading the contents of a file:

while (<PARSE>) {
    push @data, [unpack $template, $_]
}

---

#!/usr/bin/env perl

use strict;
use warnings;

my @data = ( [ 'Dave', 'Green', '5', ], [ 'Bob', 'Yellow', '4', ] );
print $data[0]->[2], "\n";  # 5
print $data[1]->[0], "\n";  # Bob

@data is an array of arrays. A hash consists of a key and a corresponding value. In order to convert the array into a hash, you have to assign one of the elements to be the key and the rest the value.

Note

Alternative syntax:

$data[0]->[1] is equivalent to $data[0][1].
