in thread array refernce as hash value

sorry some typo mistake I am trying to do somthing like this
open my $fh, '<', $filename or die "$filename: $!\n"; while (<$fh>) { + chomp; ($key, $value) = split /\|/, $_; push @{$hash_merge{$key}},$v +alue; print "key for $key merge values $hash_merge{$key}->[0]1 \n"; #file looks like 9344220001|sei10720013,21/07/2009-00-00-00,23/07/2009-12-34-44 9344220001|sei10720014,23/07/2009-20-00-23

    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
    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' ] ] };
    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
    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' ] };

    Is this, what you want, or is it not, what you want? In the latter case, what exactly do you want to have as result?
