Thanks to every individual who ever committed code to PHP or who wrote a line of code in PHP—you all made PHP what it is today.
To my parents, who once purchased a small LEGO set for a long and frightening plane trip, beginning an obsession with creativity and organization that continues to relax and inspire.
Finally, a heaping third spoonful of gratitude to Jennifer and Hadden, who continue to inspire and encourage me even as I pound out words and code every day.
I would first like to praise the Lord of Hosts who gives me the strength to face each day. He created electricity through which I make my livelihood; thanks and praise to Him for this totally unique and fascinating portion of His creation.
To Kevin, who is once again my main coauthor on this edition, thanks for the effort and desire to stick with this project to the end.
To the technical editors who sifted through our code examples and tested them to make sure we were accurate—Simon, Jock, and Chris—thanks!
And finally to all those at O’Reilly who so often go unmentioned—I don’t know all your names, but I know what you have to do to make a book like this finally make it to the bookshelves. The editing, graphics work, layout, planning, marketing, and so on all has to be done, and I appreciate your work toward this end.
