I hope this free php script can help a lot for quick import csv work: http://www.phpcsvimporter.co.uk
here the download link: http://www.lavorohotel.net/php_csv_importer_3_0_2a.zip
to install it, just edit config.php and insert db data and Absolute path to index.php of the importer script
it is opensource, and could be used for quick import and also for sample code coding the import.
good luck!
