In This Chapter
The previous chapter explored some advanced OOP concepts, with a particular emphasis on those related to inheritance. In this chapter, you’ll learn even more advanced OOP concepts, including some introduced in more recent versions of PHP. Tip: make sure you know what version of PHP you’re working with before proceeding.
The topics in this chapter get to be more esoteric, and won’t always be necessary in a Web application, but these concepts should be on your radar as you become more comfortable with OOP as a programming approach. As with the past two chapters, a fair amount of OOP theory will be covered as well.
