Re: array refernce as hash value

Do you think of something like this?

my %hash = (
    key1 => [\@a1_ref, \@a2_ref],
    key2 => [\@a3_ref, \@a4_ref],
);
[download]

If you want to use the a2_ref for instanze, $hash{key1}->[1] could be what you want.

Edit: As an example:

#!/usr/bin/perl
use strict;
use warnings;

my @array1 = ( 1 .. 6 );
my @array2 = ( 7 .. 9 );
my @array3 = ( 'aa' .. 'af' );
my @array4 = ( 'b0' .. 'b9' );

my %hash = (
    key1 => [\@array1, \@array2],
    key2 => [\@array3, \@array4],
);

print "hoffentlich eine acht: ", $hash{key1}->[1]->[1], "\n";
[download]

It prints "hoffentlich eine acht: 8".

Are you looking for something similar to : use strict; use Data::Dumper; my %hash; while (<DATA>) { chomp; my ($key, $value) = split /\\|/, $_; my @values = split /,/, $value; if (defined $hash{$key}) { push @{$hash{$key}}, \@values; } else { $hash{$key} = [\@values]; } } print Dumper \%hash; __DATA__ 9344220001\|sei10720013,21/07/2009-00-00-00,23/07/2009-12-34-44 9344220001\|sei10720014,23/07/2009-20-00-23 9344220002\|sei10720015,21/07/2009-00-00-00,23/07/2009-12-34-44 9344220003\|sei10720016,23/07/2009-20-00-23 9344220003\|sei10720017,23/07/2009-20-00-23 9344220003\|sei10720018,23/07/2009-20-00-23 [download] Output is as followed: `$VAR1 = { '9344220003' => [ [ 'sei10720016', '23/07/2009-20-00-23' ], [ 'sei10720017', '23/07/2009-20-00-23' ], [ 'sei10720018', '23/07/2009-20-00-23' ] ], '9344220002' => [ [ 'sei10720015', '21/07/2009-00-00-00', '23/07/2009-12-34-44' ] ], '9344220001' => [ [ 'sei10720013', '21/07/2009-00-00-00', '23/07/2009-12-34-44' ], [ 'sei10720014', '23/07/2009-20-00-23' ] ] };` [download] I hope this helps.

And what is youre problem with this? `#!/usr/bin/perl use strict; use warnings; my %hash_merge; while (<DATA>) { chomp; my ($key, $value) = split /\\|/, $_; push @{$hash_merge{$key}}, $value; print "key for $key merge values: ", $hash_merge{$key}->[0], "\n"; } use Data::Dumper; print Dumper \%hash_merge; __DATA__ 9344220001\|sei10720013,21/07/2009-00-00-00,23/07/2009-12-34-44 9344220001\|sei10720014,23/07/2009-20-00-23` [download] prints `key for 9344220001 merge values: sei10720013,21/07/2009-00-00-00,23/07 +/2009-12-34-44 key for 9344220001 merge values: sei10720013,21/07/2009-00-00-00,23/07 +/2009-12-34-44 $VAR1 = { '9344220001' => [ 'sei10720013,21/07/2009-00-00-00,23/07/200 +9-12-34-44', 'sei10720014,23/07/2009-20-00-23' ] };` [download] Is this, what you want, or is it not, what you want?
