INTRODUCTION Displaying a summary of a long article and linking to the full text Protecting parts of your site with user authentication You ll also learn how to process user input from every type of form element text fields, drop-down menus, check boxes, and so forth. Most important of all, you ll see how a few simple checks can guard your websites and databases from malicious attack. In this book, I ve followed the same technique that has proved successful in Foundation PHP 5 for Flash and Foundation PHP for Dreamweaver 8. Each chapter takes you through a series of stages in a single project, with each stage building on the previous one. By working through the chapter, you get the full picture of how everything fits together. You can later refer back to the individual stages to refresh your memory about a particular technique. Although this isn t a reference book, Chapter 3 is a primer on PHP syntax, and some chapters contain short reference sections notably Chapter 7 (reading from and writing to files), Chapter 9 (PHP sessions), Chapter 11 (MySQL data types and connection commands), and Chapter 13 (the four essential SQL commands). So, to return to the original question: how easy is easy? I have done my best to ease your path, but there is no snake oil or magic potion. It will require some effort on your part. Don t attempt to do everything at once. Add new dynamic features to your site a few at a time. Get to understand how they work, and your efforts will be amply rewarded. Adding PHP and MySQL to your skills will enable you to build websites that offer much richer content and an interactive user experience. It s been great fun writing this book, and the process has been smoothed all the way by the editorial team at friends of ED/Apress led admirably as ever by Chris Mills, the man with the psychedelic stuffed chicken (www.flickr.com/photos/chrismills/124635002/). Special thanks go also to Samuel Wright for his helpful technical review, Kylie Johnston for keeping the project on an even keel, Nicole Flores and Ami Knox for their sensitive copy editing, Laura Cheu for overseeing the process of turning my words and pictures into the book you re now reading, and everybody else who toiled behind the scenes. My greatest thanks of all go to you for buying this book. What do you mean you haven t bought it yet? Rush over to the checkout counter and buy it now. Then let the fun begin. If you enjoy what you re doing, then everything becomes easy.
