(*) - Sviluppare applicazioni con PHP e MySQL di Kevin Yank - APOGEO (2012)
The latest version of Kevin Yank’s book is probably a good one to go for. If you’re having a look through a number of different books down at your local bookstore, if a book uses the old and now depreciated mysql_* extension steer clear of it. Any books should be using php code that uses either the mysqli_* (MySQL Improved) extension or PDO. Whether they use the mysqli_* extension or PDO they should use prepared statements
