in reply to Re: duplicate keys on hash
in thread duplicate keys on hash

While replying to above Anonymonk I am actually clarifying to OP

But I don't see how(in example) typing in the "2" would pull up both BBB AND EEE

The possibly missing information is the syntax used above to treat the hash value - spelled out $hash{$key} - as if it were a plain array is to put it inside this thingy @{ ... } instead of the dots.

You have been shown that it gets into the hash value with the simple push function.

Getting stuff out works the same way:

foreach my $key ( keys %hash ) { foreach my $value ( @{ $hash{$key} } ) { print $key, ": ",$value, "\n" # or whatever you want to do. } }
