(^178) CHAPTER 11 ■ SPL FILE AND DIRECTORY HANDLING
The final example in this chapter demonstrated how to create a basic substring file search
engine using an iterative approach. This search facility combined directory iteration, flattening
iterators, filtering, searching, and SplFileObject subfile iteration—putting together everything
you learned about in this chapter.
In the next chapter, you will learn how to manipulate data, building on the lessons learned
so far.
