Ubuntu Servers :: Reinstall XAPP And Copy The Index.php Files From Another Comp?

First off. I'm not using Ubuntu Server. But I'm trying to get XAMPP set up so I can test Wordpress themes I make. Using 9.10. I got XAMPP installed using the Instructions from Apache Friends. When I went to Localhost I got the language page. Selected English but nothing happened.

Here's my Index.php:

Code:
<?php
if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) {
$uri = 'https://';
} else {
$uri = 'http://';
}
$uri .= $_SERVER['HTTP_HOST'];
header('Location: '.$uri.'/xampp/');
exit;
?>

Something is wrong with the XAMPP installation :-( I searched and found a couple Index.php files. Deleted one. And now when I go to localhost I get a "Index of" page.I removed the XAMPP folder, Deleted Apache, PHP from Synaptic(They got reinstalled when i reinstalled XAMPP btw). Installed LAMP but it still does it. Maybe reinstall XAPP and copy the index.php files from another Comp?.
