It looks like a lot of my ticket got cut off.

if ($wolent['interface'] == "lan")
echo "LAN";
else
echo $config['interfaces'][$wolent['interface']]['descr'];

It should be just
echo $config['interfaces'][$wolent['interface']]['descr'];

Ok, it is not quite that simple.
(I would not be surprised if there was already be a function that does this.)

if ( !empty( $config['interfaces'][$wolent['interface']]['descr'] ) )
echo $config['interfaces'][$wolent['interface']]['descr'];
else
echo ucase($wolent['interface']));
