Hi
Howdy.
Scouring the books to try and find this, but it's evading me.
How can I test whether something is an array.
For some definition of "something" that includes references, use ref().
:)
ie I have a hash and some values are anon arrays and some are strings.
I want to test to see whether one is an array and then traverse it.
if ( ref($some_hash{might_be_array_ref}) eq 'ARRAY' ) {
# ...
}
Hope that helps.

if (ref $hash{$key}) {
# do something with @{ $hash{$key} }
}
