I would like to setup a basic system on my server where a few users have their own FTP accounts. Each user will be able to upload a simple file like a text or CSV file with one record per line. I would like the system to then compare the contents of that file to a database for duplicates, and then create a new file with the contents of the database + the contents of the new file, without the duplicates which can then be downloaded by the user. It would be nice if on a per user basis we could offer the new file to be downloaded either in full, or as a 'partial' download if the user has already downloaded it once before (so just the new records would be downloaded).

The easy and better way for this purpose is by using a cron job script which will check the current existing uploaded file with the one on the database. The script will then comparing them all. But, the one I still dont know is the file name convention. Will it compare all file types or just a specific file format such as .csv or another else. Lt me know.

Hi, PHP Expert is ready to start. Will develop a PHP script to compare the user uploaded CSV file records with database records. And then allow them to download partial file containing unique records every time. Please check my portfolio and reviews for past experience. Thanks, Mayank
