Before You Begin
Before you begin reading the meat of this book, please take a moment to open the CD that accompanies this book and copy the source code to your computer. The phpwasrc/ directory contains the initial files you need.
In addition to the full source code (and installation instructions) for the three large samples from Part V of the book, there are also small snippets of code to accompany many of the chapters in the book. You can run these, debug them, or change and play with them to further help you learn how the language works.
Beyond the sample sources, the CD contains versions of PHP, the Apache HTTP Server, and MySQL that you can use to install the software on your local machine. Instructions are included on the CD.
