IMHO: always make the database manipulate the data for you, if it can. It's
usually much faster, and requires less code.
In this case just do:
SELECT DISTINCT this FROM that WHERE here
and you won't get any duplicates. Great huh? :)
Refer to the MySQL manual at http://www.mysql.com/docs/ for more details.
