XML and PHP [Electronic resources]

Conventions

This book follows a few typographical conventions:

A new term is set in italic the first time it is introduced.

Program text, functions, variables, and other "computer language" are set in a fixed-width fontfor example, <?xml version="1.0" encoding="UTF-8"?>.

Some of the listing headings include a filename (for example, Listing 4.1 Simple XML Book List (list.xml)where (list.xml) is the filename). This filename is a reference to filenames used in subsequent code listings.
