Acknowledgments

I would first like to thank all those folks at O’Reilly who are involved in books and never really get a pat on the back. I don’t even know who you all are, but thanks for all of your work to help get this project done (and done well), and to finally make it to the bookshelves. The editing, graphics work, layout, planning, marketing, and so on all have to be done, and I appreciate your work toward this end.

To Julie Steele, my acquisitions editor at O’Reilly, who always showed great patience and professionalism on this project, thanks for giving me this opportunity and for working with me from start to finish. I think I could now consider you to be one of my better friends in the IT publishing business. One day I hope to meet you in person!

Much thanks to my technical editors, too. Charles Tassell, Brian Danchilla, and Peter Lavin, thanks for your keen eyes and for thoroughly testing my many lines of sample code. Many of your great pointers and ideas were used to make this book better. Wez Furlong and Derick Rethans also contributed some technical pointers; thanks for your assistance as well.

Finally, to Susie Sedlacek, former Vice President, Global Services, Zend Corporation—thanks for being willing to put together an introduction for this book. I was keen to have you do the introduction so that readers could get a global perspective on the ever-growing, worldwide use and impact of PHP. I was happy to hear that you and your husband have purchased a vineyard in California, and I hope that you really enjoy that new endeavor!
