You can push array references into an array:

Code:

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;

my @array;
push @array, [qw/one two thee four/];

or you can push values into a specific location in an array:

Code:

push @{$array[1]}, 'a value';
push @{$array[2]}, [qw/five six/];
print Dumper \@array;

Result:

Code:

$VAR1 = [
          [
            'one',
            'two',
            'thee',
            'four'
          ],
          [
            'a value'
          ],
          [
            [
              'five',
              'six'
            ]
          ]
        ];

Note: you can only push into specific array locations if those locations are undefined or already contain an array reference. Otherwise, you will have to make an assignment instead to overwrite the existing value.

to push into a multi-dimensional array:

push @{$array_ref[0]},$values;

but how you write the code depends on how your multi-dimensional array was originally created. If you used a reference to an array to begin with you would write it like this:

push @{$array_ref->[1]},$values;
