PHP $_GET help please (a bit of a newbie question)

[steadicamop]

Hey guys, I'm just getting into PHP and have started on a site for someone, it will be dual language, and this is what I have so far:

PHP Code:

<?php
if(isset($_GET['lang']))
if($lang == "en")   {   ?>
        <div align="center">
          <p align="justify">English Text</p>
        </div> </div>
<?php 
    }      
else if($lang == "nl")
          { ?>
                <div align="center">
                  <p align="justify">Dutch Text</p>
    </div></div>
<?php } ?>

Now, I'm using index.php?lang=en or lang=nl for each one, but I can figure out where I'm going wrong - when the page loads there is no text, I want it to default to Dutch - how do I achieve this? I thought I knew how but it wouldn't work.

Is there any other easier way of achieveing this as well? I thought this was the easiest way I could find.

Cheers

Jason
