A hash reference is a scalar created using the \ operator as follows:
my %user; $user{'name'} = "hatter"; $user{'network'} = "irc.blackhatacademy.org"; my $hashref = \%user; |
Once you've created a hashref (hash reference) you must use pointers to access a key:
print $user->{'name'} . "\n"; print $user->{'network'} . "\n"; |
