I had some trouble with this topic. The script in the apply your knowledge didnt seem to work on my WAMP im currently running PHP 5.3 i did alter the code to look like this:

on session.php

<?php
session_start();

$bgcolor = $_SESSION['bgcolor'];

if (isset($_GET['color']))
$color = $_GET['color'];

if (isset ($color)) {
switch ($color) {
case "Yellow":
$bgcolor="#FFCC00";
break;
case "Blue":
$bgcolor="#4682B4";
break;
case "Silver":
$bgcolor="#C0C0C0";
break;
case "Beige":
$bgcolor="#FFE4C4";
break;
default:
$bgcolor = "white";
break;
} // end switch
}

if (empty ($bgcolor)){
$bgcolor = "white";
}

$_SESSION['bgcolor'] = $bgcolor;

?>
<html>
<head>
<title>Sessions</title>
</head>

<body bgcolor="<?php echo $bgcolor; ?>" />
<br />
<form method="get" action="session.php?<?php echo "PHPSESSID".session_id(); ?>" />
Select a background color
<br>
<input name='color' TYPE='radio' VALUE='Yellow'> Yellow
<br>
<input name='color' TYPE='radio' VALUE='Blue'> Blue
<br>
<input name='color' TYPE='radio' VALUE='Silver'> Silver
<br>
<input name='color' TYPE='radio' VALUE='Beige'> Beige
<br>
<br>
<input type="submit" value="Change Color" />
</form><br />
<br />
<a href="session.php?<?php echo "PHPSESSID".session_id(); ?>" > Refresh Page, Dont change background color</a><br />
<br />
<a href="session2.php?<?php echo "PHPSESSID".session_id(); ?>"> To Other Page </a>
</body>
</html>

This worked for me because session_register is deprecated.

and session2.php

<?php
session_start();

$bgcolor = $_SESSION['bgcolor'];

if (empty($bgcolor)) {
$bgcolor = "white";
}
?>
<html>
<head>
<title>Session Example</title>
</head>

<body bgcolor="<?php echo $bgcolor; ?>">

What color is my background?<br />
<br />
<a href="session.php?<?php echo "PHPSESSID".session_id(); ?>" /> Back to form </a>
</body>
</html>

Is this acceptable according to the course Mac?

There is no correct way to write your code - although there are guidelines and best practises. If it works, then it works!

Remember the code in the manual is PHP4 therefore you had to upgrade your code... which is what you achieved and therefore a lesson learned smiling smiley

Thanks Mac much appreciated, I see now why they call php a open source language it can be easily adapted to suite your needs if you stick to the guidelines and best practices as you mentioned above. smileys with beer
