WP-CONFIG -PHP problem

Thank you for your feedback …
Off course, I will never use root as user and an empty password … 🙂
Trying to test the script with XAMPP on my local development environment …

The problem is, that the script always runs the “default” case only! 🙁

Here’s my complete wp-config:

<?php
/**
 * The base configurations of the WordPress.
 *
 * This file has the following configurations: MySQL settings, Table Prefix,
 * Secret Keys, WordPress Language, and ABSPATH. You can find more information by
 * visiting {@link http://codex.ww.wp.xz.cn/Editing_wp-config.php Editing
 * wp-config.php} Codex page. You can get the MySQL settings from your web host.
 *
 * This file is used by the wp-config.php creation script during the
 * installation. You don't have to use the web site, you can just copy this file
 * to "wp-config.php" and fill in the values.
 *
 * @package WordPress

You mean like this: ???
<?php
$host = $HTTP_HOST;
$parts = explode(‘.’,$host);
if ($parts[3] = ”) {
$domain = $parts[0];
} else {
$domain = $parts[1];
}

print_r($host);
print_r($parts);

exit(0)
?>

Script:

<?php
$host = $HTTP_HOST;
$parts = explode('.',$host);
if ($parts[3] = '') {
$domain = $parts[0];
} else {
$domain = $parts[1];
}

print_r($host);
print_r($parts);

exit(0);
?>

Result:

Notice: Undefined variable: HTTP_HOST in C:\xampp\htdocs\vartest.php on line 2
Notice: Undefined offset: 1 in C:\xampp\htdocs\vartest.php on line 7
Array ( [0] => [3] => )

Ok, we are getting closer …
The site is starting and top left I see the $print_r():

( [0] => german-lightning [1] => loc [3] => )

removed them, but still the switch executes “default” only 🙁

True!
