How to use an array for this?

Hi everyone!

I know how to use an array to rotate items, but I need to do something slightly more complicated:



What I want to do is rotate the top row with the bottom row when the page is refreshed. I think I can do it with seperate arrays, but I'm not sure how to set it up. The only way I now how to set up an array is this:

<?php
$links = array(’http://www.link1.com’,'http://www.link2.com’);
$link = $links[array_rand($links)];
echo “<meta http-equiv=’refresh’ content=’0;url=$link’/>”;
?> 

PHP:

How would I change this so that it would flip the table contents back and forth?

Thanks!

 

If there's only 2, do a if else statement.
