This is what I currently have at the very beginning of my header page. Thanks to `Mace. Problem now is that I want to be able to toggle from english to french. I am guessing that I need to be able to restart the session, but a bit confused on how to start my script. Is it a complicated thing?

<?php
	session_start();
	
	//make sure that we have a language selected by using session .. 
	  if (!isset($_SESSION['lang'])) { 
	  /* you can either show error message and terminate script 
	    die('No language was selected! please go back and choose a langauge!');*/ 
	  //or set a default language 
	    $_SESSION['lang'] = $_GET['lang']; 
	  } 
//always do this
$lang = $_SESSION['lang']; 
	//directory name 
	  $dir = 'languages/'; 

		include_once($dir.$lang.'.inc');
?>
