Using arrays with forms is in a faq:
  http://www.php.net/manual/en/faq.html.php#faq.html.arrays

How do you feel this should be expanded?  Mentioning that
unchecked checkboxes do not pass values, and that the
default value is 'on' (if checked) ... would be good too.

I remember posting some information on this topic in the past:
  http://marc.theaimsgroup.com/?l=php-general&m=101142826821051
  http://marc.theaimsgroup.com/?l=php-general&m=98576486229922

Anyway, I agree, just not sure if there should be one specific
faq for each form type, such as checkboxes or select boxes or... 
Ideally one faq would explain it for all types, checkboxes or
otherwise.  Making it short/concise and understandable for all
user levels (such as newbies) is the tricky part.  Well,
actually, the tricky part is convincing people to read faqs :)
