update a php file


I currently have a php file that uploads a csv document to a database, I need this to be edited slightly so that it only UPDATES the database and not inserts a new row.

It must only insert a new row if the data does not exist

so for example, if I upload a csv file for January and then want to upload another document for January it must just update the information,

if i upload a csv file for february then it can insert the new information
