When developing Web applications, it is very likely that you will encounter file--csv data in different formats, password files, XML-encoded content, and different forms of binary data. Your PHP scripts will need to interact with these files frequently, reading data from them and writing data to them. Because there are so many formats of files to process, so you do not accidentally PHP has a number of types of built-in functions and external libraries
