While you can't reference the key by number, You can use foreach to pull elements.  This will be in order.   So getting the key with array_keys should work in the preferred order too.  I've added a few extra lines of commented code for reordering the array into one(s) that reference the language by number (if you need it)   :D

$_SERVER["REMOTE_USER"] and $_SERVER['PHP_AUTH_USER'] is the same variable i think..

I don't see the $_SERVER["REMOTE_USER"] listed in this document.
This displays the username used to login using .htaccess.

Matt Johnson says that one should never urldecode() $_GET data. This is incorrect.

If magic_quotes_gpc is turned off in php.ini, then you *do* need to urldecode() $_GET data.

Having magic_quotes_gpc turned off is considered good practise.
