Here is an easy way to rotate the advertisements on your site.
First off, The code:
<?php
$img = array();
$img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
$img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
$img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
$max = count($img) - 1;
$count = rand(0,$max);
echo $img[$count];
?>
Now instructions on customizing for your use.$img = array();
$img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
$img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
$img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
$max = count($img) - 1;
$count = rand(0,$max);
echo $img[$count];
?>
$img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
$img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
$img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
All you have to do is edit these to what your advertisements are. You can add more advertisements to be rotated by copying and pasting one line of the code. $img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
$img[] = '<a href="http://www.website.com"><img src="link-image.gif" /></a>';
To display this, Save the file as ads.php and inlcude the page where you want the advertisements to be displayed at
<?php
include('ads.php');
?>
include('ads.php');
?>
Thats about it, Contact me if you are unable to get this to work or if you don't understand a part of the code.
