Question

I am a complete PHP newbie, and I’m not even sure if I should be using PHP for what I’m doing, but here goes. Basically all I want to do is based on where a user comes from, change a link on the page to link to another location. I feel like this is very basic, but I’m not sure exactly how to phrase my search to get the best results. How would I do this?

You probably want something along the lines of

<?php if ($_SERVER['HTTP_REFERER'] === 'http://www.example.com') { ?>
  <a href="http://www.example.com/1">1</a>
<?php } else { ?>
  <a href="http://www.example.com/2">2</a>
<?php } ?>
