Hi,

I'm new to PHP and since I'm setting up a website using Joomla 2.5, I need some basic understanding of PHP. But when I run the following code, from a book I'm using as a intro text, nothing is displayed on Firefox (version 18).

Code:
<html>
<head><title>PHP says hello</title></head>
<body>
<b>
<?php
echo "Hello, World!";
?>
</b>
</body> 
</html>
I've checked out phpinfo() to the extent of my limited understanding and I can't see anything obviously wrong.

Any help would be much appreciated
