Forms and PHP
One of the most popular ways to make a web site interactive is the use of forms. With forms you can have users register for different things, submit any information you can imagine, upload files, and all types of other things. In this tutorial, we will go through the basics of forms and how to handle the data that comes from those forms with PHP.

For the scope of this tutorial, I will assume that you have a basic knowledge of HTML and PHP. Though, you can probably get by without a great understanding of either. I will cover several different form elements, including textboxes, checkboxes, select (or drop-down) boxes, radio buttons, and textareas.

In this tutorial, I am going to show you how to access the information that has been entered into a form. It is up to you to decide what you want to do with it. You can put that information into a database, a flat file, email it off, or countless other things. All I will be showing you is how to get to that data.

Ok, enough of that. Let's get to it!
