Conventions Used in This Book
Programming Conventions
We've generally omitted from examples in this book
the <?php and ?> opening and
closing markers that begin and end a PHP program, except in examples
where the body of the code includes an opening or closing marker. To
minimize naming conflicts,
function and class names in the
PHP Cookbook begin with pc_.
The examples in this book were written to run under PHP Version
4.2.2. Sample code should work on both Unix and Windows, except where
noted in the text. Some functions, notably the XML-related ones, were
written to run under PHP Version 4.3.0. We've noted
in the text when we depend on a feature not present in PHP Version
4.2.2.
