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!
