title: Simple weighted link rotation?
body: <p>I'm split testing landing pages in campaign currently by sending them to the following script:</p>
  
  <pre><code>$link[] = "http://www.website.com/lp1";
  $link[] = "http://www.website.com/lp2";
  
  $random_number = rand(0,count($link)-1);
  $redirectlink = $link[$random_number];
  
  header("Location: $redirectlink");
  </code></pre>
  
  <p>If I wanted to have the first LP shown 75% of the time, how do I go about doing that? Will simply replicating that first link two more times work, or is there a better way to go about it?</p>
