In this hour, we introduced PHP. You learned the history of PHP from a simple set of macros to the powerful scripting environment it has become. You found out about PHP and the Zend scripting engine, and how they incorporate new features and more efficiency. Finally, you discovered some of the features that make PHP a compelling choice as a Web programming language.
I hope that you've been convinced by this chapter that PHP is the language for you. In the next hour, we dive straight in and install the PHP engine.
