I'm completely new to PHP and MySQL so I"m not familiar with editing the PHP.ini file. Could you walk me through that?

I believe step 5 on page 106 has an error. The code in the book is:

<?php
switch (isset($_GET['content'])) :
case 'gents' :
case 'sporting' :
case 'women' :
include 'content/catnav.php';
endswitch;
?>

This always evaluates to 'TRUE', so the catnav.php is always included on all pages. I believe the correct code should be:

<?php
if (isset($_GET['content'])) :
switch ($_GET['content']) :
case 'gents' :
case 'sporting' :
case 'women' :
include 'content/catnav.php';
endswitch;
endif;
?>

I'm really enjoying the book.

The php.ini file is a straight text file so you can edit it in Notepad or any code editor (just not a word processing editor like Word). There could be multiple php.ini files -- there will be one that covers php in general and then you could also have one that overrides certain commands more local to your site.

The online PHP manual contains more complete information: http://php.net/manual/en/configuration.file.php

Thanks for pointing that out. There's nothing more frustrating than a mistake in the code examples when you are learning a programing language. I'll get that added to the errata.

The code in the downloadable code files has the correct code, I'm happy to say.

I'm glad you are enjoying the book. :)
