hashes - perl

can anyone tell me how to create a hash of hashes , and then get the values out again!

eg hash1 = (key1 = hash1a (key1a => value,
key2a => value));

not sure how to format it!!:confused:

If I'm not mistaken...

Code:

---

my %hash;

$hash{$myKey} = {};
$hash{$myKey}->{$someOtherKey} = $someOtherValue;

You can check at PerlMonks.

thanks

as it happens i've just found the perl monks article on this!!

any idea how you get the values out using a foreach loop?

Just a guess.

Code:

---

foreach $key (keys(\$hash($myKey))) {
  #do work
}
