[PHP] Uploading a csv using php


I just started learning PHP last week and have made some good progress. However, I do not know how to begin to upload a csv file using php. I've found some example code, however I'm not sure how to apply it. I would greatly appreciated if someone could lay out the general process or code as to how to attempt this. My csv file has 10 rows and 32 columns of data in decimal format.

In debt to all,
