Been studying your book for a while and noticed it is not too much different from the 4th edition. The book's using mysqli_ for database connection, and the php is still version 5.some. Meanwhile, php 7 has come to life and the pdo is ubiquitous nowadays. As well as MVC and more or less object oriented approach in general. Some books i know of (i'm not sure if i can mention them here) went through this and even their hands-on practice evolved from developing a simple CMS to an almost framework-like application. So, my question is: will you update your PHP & MySQL series?
