75674 list processor

Here are the steps i need the scripts to do. 1. User uploads a file in any text format. TXT, CSV, TAB DELIMETED. 2. The script will then search the file for email addresses and add them to a database named database1 for the example. 3. once it has added all the email addresses to database1 it will then compare database1 with database2(which already has email addresses in in) to see if the same email address is in both databases. 4. The server will then create a file of the duplicate email addresses for the person to download. The most important thing is that the server only checks the email addresses that the person uploaded and not the whole database1, because database1 will also have the emails that everyone else has uploaded.
