But, why do you need to receive explicitly both checked and unchecked
options in the first place? You are supposed to know what the available
options are and whatever option does not show up as checked, well, it
must be unchecked.

I presume *you* know the options but your PHP code doesn't. In this
cases, it can be useful to define an array at the top of your code:

$options = array(
// Code name => Descriptive label
'boksin' => 'Receive the Boksin newsletter',
'boksil' => 'Receive the Boksil newsletter',
'boktav' => 'Receive the Boktav newsletter',
'boklic' => 'Receive the Boklic newsletter',
'bokncg' => 'Receive the Bokncg newsletter',
'bokpap' => 'Receive the Bokpap newsletter',
);

You can then use this data array to:

1. Print the appropriate checkboxes
2. Validate user input
3. Derive unchecked options

switch() and foreach() are your friends :)
