I have very little knowledge on MySql and Php. And i am really very confused. Plz i want to revise it and need some help. Plz post a step by step tutorial on MySQL and PHp from basic to advance level.

Just search for PHP and/or MySQL (beginners) tutorials on the web.
Some hints:
http://devzone.zend.com/node/view/id/627 (recommended)
http://www.php.net/ (a must for everything PHP)
http://www.sqlcourse.com/

And/or get yourself a book at your local bookstore. I'm currently reading "PHP and MySQL Web Development" by Luke Welling, Laura Thompson. It helped me a lot by doing the exercises of the book.

[edit] correction of author's name.

There are some really good tutorials at lynda.com on PHP and MySQL
