I realise I'm a bit behind the curve on this, but this looks like a
rather convoluted way of doing what you want to do. However, it's rather
difficult to tell without *specifics* -- can you post the output from
var_dump($book_categories) and var_dump($category), and a snippet of
what you want the eventual output from that to look like, so we can
actually work out the most efficient route from one to the other?  (It
might also be helpful to know where $book_categories and $category come
from originally -- are they the results of a database query?)
