In the vast ocean of bad PHP programming books that serve only to perpetuate bad programming habits in the world of PHP, there are few PHP books that I would recommend more than George Schlossnagles’ Advanced PHP Programming. In Advanced PHP Programming George takes us all the way from simple (yet very important) syntax rules and standards, to advanced object oriented design patterns, profiling and debugging your php code, data caching, extending php and much much more. This insightful book illustrates the importance of security in PHP development and gives you many wonderful tools to develop large scale php applications. I would definitely give this book 2 thumbs up and highly recommend it to anyone wanting to break free from the typical PHP tutorial books. Anyone who wishes to get into the meat of PHP web development should read this.
