While it would be interesting to delve into the details of the content-submission system described above, you should already have all the skills necessary to build it yourself. Want to let users rate the jokes on the site? How about letting joke authors make changes to their jokes, but requiring an administrator to approve the changes before they go live on the site? The power and complexity of the system is limited only by your imagination.
At this point, you should be equipped with all the basic skills and concepts you need to build your very own database-driven Website. In the rest of this book, I'll cover more advanced topics that will help optimize your site's performance. Oh, and of course we'll explore more exciting features of PHP and MySQL.
In "MySQL Administration", we'll take a step away from our joke database and have a close-up look at MySQL server maintenance and administration. We'll learn how to make backups of our database (a critical task for any Web-based company!), administer MySQL users and their passwords, and log into a MySQL server if you've forgotten your password.
