Hi,
I have been going through the lessons/examples but am stumped on the first dynamic script on page 36 (script 1.5)
Here is what I wrote:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML
1.0 Transitional//EN" "http://www.w3.org/
TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xml:lang="en" lang="en">
<head>
<meta http-equiv="content-type" content=
"text/html; charset=iso-8859-1" />
<title>Predefined variables</title>
</head>
<body>
<?php
# script 1.5 predefined.php
# May 21 2011
// Create a shorthand version of the variable names:
$file = $_SERVER[‘SCRIPT_FILENAME’];
$user = $_SERVER[‘HTTP_USER_AGENT’];
$server = $_SERVER[‘SERVER_SOFTWARE’];
// Print the name of this script:
echo "<p>You are running the file:<br /><b>$file</b></p>\n";
// Print the user’s information:
echo "<p>You are viewing this page using:<br /><b>$user</b></p>\n";
// Print the server’s information:
echo "<p>This server is running:<br /><b>$server</b>.</p>\n";
?>
</body>
</html>
And I get nothing. The page is here: http://matrixfiles.com/lu/predefined.php
On my computer webserver (Wamp) I get this page (screenprint):
This has completely puzzled me. Anyone know what I am doing wrong? I have double checked the code and nothing seems to be out of place.
