I cannot comment on the rest of your post right now, but if you are checking 
for the existence of a bunch of keys in an associative array and setting 
defaults if they are not set, the following will be considerably faster and 
easier to read:

$my_array += array(
  'a' => 'A',
  'b' => 'B',
  'c' => 'C',
);

That will set $my_array['a'] to A iff it doesn't exist, ['b'] to B iff it 
doesn't exist, etc.  That is far nicer to read than a bunch of ternaries, 
short-circuited or no.  You can even stick the defaults array into a function 
and call it from various places to ensure your array always has the same sane 
defaults.
