Chapter 13. Web Applications and the Internet

Now that we have covered the basics of programming with PHP and MySQL, it is time to turn our attention to the task at handwriting web applications. Before we begin to show you some of the techniques and tools for doing this, we are going to spend time discussing many of the key concepts, considerations, and issues to keep in mind when writing them.

Over the course of this chapter, we will

  • Discuss the technologies and protocols that make up the World Wide Web and learn how they work

  • Define web applications and discuss how we will structure them

  • Learn about 3-tier and n-tier architectures, including what might be placed in each tier

  • Spend some time covering performance and scalability of our web applications
