CHAPTER 11

SPL File and

Directory Handling

The SPL provides several classes and iterators that allow for object-oriented access of files and

directories. In this chapter, you will learn about how the traditional file-access functions of PHP

have been transitioned to object form.

Iteration plays an important role in working with files and folders. In this chapter, you will

be introduced to several advanced iteration techniques for listing, searching, and filtering files

and directories.

Finally, the SPL provides the ability to manipulate the content of files. It allows you to parse

INI files, search using regular expressions, read comma-separated value (CSV) data, and so on.

This chapter provides comprehensive examples of how to manipulate files in your applications.

File and Directory Information

The purpose of the SplFileInfo class is to provide object-oriented access to the properties of a

file or directory. It is defined as shown in Listing 11-1.
