[PHP] header switching for languages

[Lapras]

I am looking to change the specific lines of uniform parts of the code depending on which language the user wants the page in.
Example index.php?lang=ru
index.php?lang=en

Here's some code for you:

<?php
switch($_GET['lang']) {
default:
include "english.php";
break;

case "ru":
include "russian.php";
break;
}
?>
