AUDIENCE
This book is an introduction to the advanced features new to PHP 5. It is writ-
ten for PHP programmers who are making the move to PHP 5. Although
Chapter 2, “PHP 5 Basic Language,” contains an introduction to PHP 5 syn-
tax, it is meant as a refresher for PHP programmers and not as a tutorial for
new programmers. However, web developers with experience programming
other high-level languages may indeed find that this tutorial is all they need
in order to begin working effectively with PHP 5.
