How do I manipulate array references?
In a package I'm writing I initialize an array reference (I think) through DBI like this:
$self->{author_ids} = $dbh->selectall_arrayref($query);First of all, what sort of foreach loop can I write to iterate through the contents of $self->{author_ids}?
Second, how do I undefine the value of $self->{author_ids}?Third, if I have a list of integers, how to I assign the items in this list to $self->{author_ids}?
