Working with percentages in PHP
<p>I'm trying to create a simple split tester in PHP but I'm having some trouble getting the percentages all figured out.</p>

<p>So, I have a settings page where I want to put a percentage, something like 20, so that 20% of the traffic to my page will be redirected.</p>

<p>This will obviously need to work with rand, but I'm not exactly sure how.</p>
