If you want to UPDATE several rows then you must have unique identifiers for those rows. If you don't then I'm guessing what you actually want to do is INSERT those rows.
It's off-topic in the same way as asking a mechanic how to fit a bunch of stuff in your car. It's the MySQL part that you're having a problem with, not the PHP. I strongly recommend that you use the MySQL command line to run the queries you think you need to run, checking what the table looks like after each one. Once you know what queries you need to run you will more effectively be able to write the PHP wrapper around those queries.
