Needing effectively a three-way flag, I think I'd think a bit outside
the
box and go with something like (untested, but the general principle is
right!):
$count = FALSE;
foreach ($authors[$bookID] as $authorID=>$authorData):
if ($count===FALSE):
$count = count($authors[$bookID])-1;
elseif (--$count):
echo ', ';
else:
echo ' & ';
endif;
echo $authorData['first_name'], ' ', $authorData['last_name'];
endforeach;
Cheers!
