You will get a cold response from the regulars on this list if you "ask
questions that have been asked gazillions of times before". Friendly
advice: always take a little time to search the archives of this list and
google a bit to see if your question has already been answered. Can you
imagine what this list would be like if every newbie asked the same
questions every day? That said, on to your questions.

You will not be able to do what you propose with a purely PHP solution. PHP
is a server-side technology. That means all the processing is done at the
server, then output to your browser. PHP, to my knowledge, has no way to
inspect your computer's folders. You would need to look to a client-side
technology, like Java, for that.
However, you can upload data to your website using PHP to process the
uploaded file. So, at your convienience, you can have a "Browse" button on
an update page that will allow you to browse and find your data to upload.
After the upload you can have PHP process the uploaded file any way you
wish.
You can also use cron to kick off scheduled tasks with PHP CLI scripts that
will, for instance, open an FTP connection to your machine and download data
files to the server for processing.
