Re^3: importing all the values stored in an HoH into an array

keys is a function for pulling out all the keys from a hash. There is also a values function for ... er ... pulling out the values. You should also be aware of each. Here is an example.

use strict;
use warnings;

my %dets = (
   name => q{fred},
   age  => 33);

while (my ($key, $value) = each %dets)
{
    # Do something with key and value here
}

Note that you can't predict the order in which these functions will present keys, values or key/value pairs.

I hope this is of use.

Cheers,

Thank you for the example. It makes sense that there would be no predictable order for how keys, values, or key/value pairs are presented because a hash is not indexed like an array is. Still, these three tools will be most useful in my future dealings with hashes. cheers -mox	[reply]
