Now the PHP code we wrote in Chapter 10 truly does what it is supposed to. Congratulations. Our trivia game now has a Flash interface that reads questions from a database somewhere. That's really cool.
Our PHP script obtains questions from a database and sends them out in XML. In this chapter, we learned how to have PHP connect to a MySQL server, obtain results from the server, and then parse the results. Further, we extended our knowledge of MySQL a little by learning about some group commands.
We also went through two versions. This experience taught us to try to eliminate loops whenever for extra speed.
