I need a PHP script that will allow a user to select and upload a csv file and then be able to map the csv data to the correct fields in the database like zoho CRM does in importing..
During the import process I would like the script to detect any duplicates(some options with skip, clone, overwrite) in the database. For more info you can check ZOHO CRM importing feature. Especially, check the steps.
The data that will be imported will be names, street addresses, phone numbers and email address etc.
