Chapter 11: Working with Files and Directories
In the next chapter you are introduced to another popular way of storing application data: databases.
This is quite a big topic, so it ’ s spread over the next three chapters. Chapter 12 introduces the concept of
databases; Chapter 13 shows how to read data from a database; and Chapter 14 shows how to
manipulate data in a database.

Before leaving this chapter, try the following exercise to test your knowledge of file and directory
handling in PHP. You can find the solution to this exercise in Appendix A.

Exercise

Create a PHP application that can be used to find a particular directory by name when given a top - level
directory to search. Make the application look through the given directory, as well as all directories
under the given directory.
