To get the most out of this book

To get the most out of this book, you must have a basic understanding of PHP syntax, variables, control structures (for example, if {} else {}), looping structures (for example, for () {}), arrays, and functions. You must also have a basic idea of PHP OOP: classes, inheritance, and namespaces.

If you have not received formal PHP training, or are unsure that you have the necessary knowledge, please review these two sections of the online PHP reference manual:

• PHP OOP:
