Sync CSV files with MySQL Database.

Hello mates, Perhaps this seems to be a silly question, but it is not to me, here is the scenario: I know how to import CSV files with PHP to a MySQL database, the thing is, that CSV file is automatically feed by a third-party application, I want to do something to add just the new records, not all the records again. Any idea or example, will be really appreciated. Thanks! -- Carlos Sura.- www.carlossura.com www.carlossura.com/blog
