First, what do you see if you view the page source in Firefox? Do you see
your original PHP code, or is it just blank? If you see PHP code, it would
mean that your server (Apache, nginx, etc) is not configured to process
PHP code.
Second, does the database user you use to connect with actually have
access to the database you're selecting?
If you don't see PHP code in your page source, you might have errors in
your query or database connection. To see the errors, I suggest you
temporarily enable error reporting to see any hidden error messages. You
can do this in runtime by putting these two lines at the top of your first
<?php code block:
ini_set('display_errors', 'stdout'); // if you're using PHP older than
5.2.4, use '1' instead of 'stdout'
error_reporting(E_ALL);
Since there aren't any syntax errors in the script you pasted above, this
should output all error messages (even notices) to your HTML document.

Make sure the .php file is readable by all users ("chmod a+r filename.php"
from the command line, or right-click - File Permissions in FileZilla).
Also, it may be that the /var/www directory has been set to not be allowed
in the webserver configuration (if this is the case, though, even not
specifying a file name in the URL would give the "Permission denied").
