in a database or what?

yes..in database

Member Avatar for somedude3488

use 'unique' on the column in the database. it won't allow the same data twice in that column.

Use SELECT DISTINCT in the query. This will discard duplicate rows. It is better to set constraints like mentioned above to eliminate duplicates from being inserted though.
