Simple Login/Register System

I require a simple login system using preferably PHP and MySql*. A system which can automatically run by its self, registering such user via a form on my website.... checking the data is valid.... adding the user to a MySql Database.... Sending an email to the user using the email input.... allowing the user to securely login to their own unique account.... A system which can allow me to edit the data etc the user see on their account easily as creating a simple website page.... I also would like you the creator to upload the files etc to reduce problems etc. No design is needed just the simple inputs and needed elements etc
