title: URL rotator in specific order
body: <p>I want to create an URL rotator script that will rotate my URLs in a specific order,not randomly.</p>
  
  <p>let say I have 100 URLS to rotate, I have them ordered and the rotator will show them from the first one until the last one, then return to the first URL and so on.</p>
  
  <p>if possible can it be a simple php script with no database?</p>
