Are you quite certain you don't really want a Hash of Hashes?

    Record another vote for a hash of hashes.
    #!/usr/bin/perl -w use strict; print "Content-type:text/html\n\n"; my @array = qw(var1 var2 var3); my %HoH = (); my $i = 0; foreach my $element (@array){ $i++; $HoH{$element} = { 'key'.$i.'1', 'value'.$i.'1', 'key'.$i.'2', 'va +lue'.$i.'2', 'key'.$i.'3', 'value'.$i.'3' }; } foreach my $key1 (sort keys %HoH){ foreach my $key2 (sort keys %{ $HoH{$key1} }){ print "<br>$key1 > $key2 > $HoH{$key1}{$key2}\n"; } }
    Output:
    var1 > key11 > value11 var1 > key12 > value12 var1 > key13 > value13 var2 > key21 > value21 var2 > key22 > value22 var2 > key23 > value23 var3 > key31 > value31 var3 > key32 > value32 var3 > key33 > value33
