For hack 16 it should be noted that:
The startlink function fails to increment nextid. It now reads:

function start_link( $text )
{
  global $nextid;
  $nextid++;


(102, 103) Second Paragragh;
The author uses the imagecopyresized() function to make image thumbnails, but in 
practice this results in terrible-looking images. Switching to the function 
imagecopyresampled(), takes the same arguments and produces a much better looking 
image. Side by side, the difference between the functions is quite astounding, 
especially when looking at an image that you only cut the dimensions in half.

Replaced imagecopyresized with imagecopyresampled.


{233} 3rd line in "Running the Hack";
"mydb" is incorrect since "transtest" is used in trans.php.

'mydb' has been changed to 'transtest' 
 
 
{239} Example 6-18. The logout handler;
the code now reads:

<?php
session_start();
$_SESSION = array();
session_destroy();
header( "Location: index.php" );
?>


(247, 249) Last paragraph in p.247 and 1st paragraph in p.249;
management.php now reads manage.php. 


[272] Sampe code for using Net_Get();

After 

$geo = new Net_Geo(); 

added the line:

$res = $geo->getRecord($ip);

 
(407) Just below middle of the page, in the "foreach ($images as $img)" loop;
The last line of the loop code looks like:

img: "<?php echo ($img['img']) ?>" },

The "," at the end causes a web browser to stop printing icons
after the first iteration. The comma has been removed and now results in the correct code execution.

Note that the download code from the O'Reilly site dated
05-Dec-2006 also has this bug in it. Removing
this comma verified proper functionality.
