This very didactic book exposes the general concepts of programming and applies to PHP with a few well-chosen examples. It then describes MySQL and its joint use with PHP. Virtually every important aspect of a web application requiring the use of a database are discussed. Details of facilities and PHP and MySQL configurations are clear but do not replace specialized books including MySQL. So it's a good book for beginners in this type of applications, but we can blame him to dwell too much on the basics of programming because I do not think a person who never makes programming tackles development (though complex) of advanced web applications.
