Jason is the author of several books, including the bestselling Beginning PHP and MySQL: From Novice to Professional (currently in its third edition), Beginning PHP and PostgreSQL: From Nov- ice to Professional, and Beginning PHP and Oracle: From Novice to Professional. He has over 100 articles to his credit within prominent publications such as Developer.com, Linux Magazine, and TechTarget.

Acknowledgements Ernest Hemingway once offered a particularly sober assessment of his trade, saying, "There is noth- ing to writing. All you do is sit down at a typewriter and bleed." This being my fifth book, and the first published under my eponymous press, W.J. Gilmore LLC, I can sympathize with his appraisal. Thankfully, psychological first aid is readily available from the family, friends, and colleagues who always make this process much less painful. Chris Davis did an excellent job as a tech reviewer, catching numerous mistakes made as I fought with both code and prose. Carlene DeFiore helped out immensely, reviewing chapters, helping with promotional strategy, and keeping me well fed. Countless other individuals played key advisory roles in helping this book to finally see the light. In alphabetical order, they include David Futato, Jonathan Hassell, Stu Johnson, and Matt Zenko. I'd also like to thank the great people at the Grandview Heights Fifth Third Bank and U.S. Post Office for helping get the business off the ground. I'd perhaps never have gotten into the publishing business without the help of Apress cofounder Gary Cornell, who first contacted me back in 2000 to write a book for what was then a very small but dar- ing computer book upstart (one which has since grown into a rather large but still daring publisher). He played a pivotal role in my development as an author and later an editor for Apress. Thank you Gary. Last but certainly not least, I'd like to thank you dear reader, for having enough faith to trade your hard-earned money for this book.
