Many websites use a system of user verification that requires everyone who signs up to provide an email address, and then click a link sent to them to 'activate' their account. Though simple, this is an effective way to limit bogus account creation, and provide some security for your user-based web service. In this tutorial we'll cover how to set up such a registration process using PHP and MySQL. It's simple! We'll write just a little bit of HTML to create forms, and then use PHP to code for the logic of what we want to happen. A basic understanding of PHP, HTML and MySQL is all that's needed to follow along.
