Your questions are well-covered by the manual, especially here:

http://www.php.net/manual/en/language.variables.external.php http://www.php.net/manual/en/reserved.variables.php#reserved.variables.post
http://www.php.net/manual/en/language.types.array.php

The PHP manual is very well-written and helpful for people who are used to other programming languages. If you have no previous programming experience, I'd suggest to go to the local library (if you have one) or a book shop and borrow/buy a book about the basic concepts of computer programming. It will be wortwhile and save you a lot of time in the long run.
