Both offer developers an amazing array of features, yet have managed to remain very approachable even among the most novice developer. In the latest edition of this bestselling book, you'll learn all about PHP and MySQL, setting you along the path towards creat- ing the web site you've long dreamed about. I begin with a vast overview of PHP's capabilities, starting with in-depth instructions of the installation and configuration process. Next, I devote several chapters to fundamental PHP concepts, including variables, data types, func- tions, and object orientation. I also introduce key concepts such as HTML form processing, session handling, and AJAX. This new edition also introduces you to several of PHP's latest features, including namespaces, enhanced input filtering and validation, and improved configuration options. I then introduce many of MySQL's key features, beginning by guiding you through MySQL's installation and configuration process. Next, you'll learn about MySQL's storage engines and data types, administration utilities, and security fea- tures I'll also introduce you to several advanced features such as triggers, stored procedures, and views. Along the way, you'll gain insight into PHP's ability to com- municate with MySQL, and you’ll learn how to create and execute queries, perform searches, and carry out other key database tasks from within your web site. Whether you're a newcomer searching for a thorough introduction to these popular technologies or a seasoned developer in need of a comprehensive refer- ence, this book is for you. W.
