You still haven't told us what you are really after. 'Counter' is a
rather undescript variable name, and $router is just an IP address, so
are you trying to count the number of times the IP occurs in a log,
etc.? You haven't stated why you need an array associated with $router
at all... the reason this is unclear is because of the name "Counter"
which implies just a count, which implies a number, which implies a
scalar, which if you really do need an array, this may suggest that your
variable name is not terribly stylish...
You have stumbled on references, which is a good thing in the end, but
you need to first establish if you truly need an array, if you have in
fact established this, then you should become familar with the core of
references before leading yourself down the path of lots of questions. A
look at,
perldoc perlreftut
perldoc perllol
perldoc perldsc
perldoc perlref
Will probably help you the most...
To specifically answer your question you can initialize the "slot" in
the hash with an anonymous array reference like so:
$Counter->{$router} = [];
Then as your other message suggests you can act on that array in ways
such as,
push @{$Counter->{$router}}, 'My latest value';
foreach my $value (@{$Counter->{$router}}) { # do something }
Or individually as,
$Counter->{$router}->[0]... but seriously read the docs....
