There are many ways to go about authenticating a user for your site, some are more secure than others. The one that will be discussed here is doing the authentication from a MySQL database.

To begin with, we will help you create the database that we will use to authenticate off of. Keep in mind, this is a very simple tutorial and there are many other ways for you to do this. Obviously, you'll need MySQL up and running on your machine and know a bit about how to use it. If you don't know how to use MySQL yet, poke around on the net and look for an introduction. I'm sure there is one somewhere.

On numerous occassions I have been asked how to serve images from a non-web accessible directory. A lot of sites now a days sell content and with the latest in php technologies like sessions and such, people like to use session management and authentication on their websites, without using .htaccess files in their directory. The easiest solution to protecting images is by reading them from a directory outside the document root on the webserver and serving it to another php script. This helps in two ways.
1. People cannot link directly to your images via a URL.
2. You can use another script to serve the image and make people login to view the image as well you could use your own html design dynamically around the image.

The goal of this tutorial, as you probably guessed by the title, is to help you (yes you) create your very own news-driven web site. Now, this doesn't have to be a system as glorified as something like Slashdot or some of the other big news sites. All you may need is a simple system for displaying news and for editing/adding news to the front page. Well, look no further - I will show you how to create a nice simple news-driven site using nothing but some pretty simple PHP and a MySQL database. Now, this can be done without a database by using a text file or something, but that's a bit more difficult. You'd have to write something to parse out the info you needed and something to put it in the right place when you were adding to it. For the sake of ease, we're going to use a simple MySQL database.
