Image Rotation

In this small tutorial, we'll learn how to rotate images in an array. This can be very handy with websites that have advertising programs. You should have a very basic knowledge of how PHP works, and your server doesn't need anything special - just PHP.

To start off, we need to create an array. In this we will place all of the images we wish to be rotated.

<?php
 $images = array(
 'http://www.host.com/image.gif',
 'http://www.host.com/image2.gif',
 'http://www.host.com/image3.gif',
 'http://www.host.com/image4.gif'
 );

Now that we have that under our belt, let's setup the randomizer. We'll be using the function array_rand().

$image = $images[array_rand($images, 1)];

And finally, let's display the image in a proper image tag, and close off the document.

echo '<img src="' . $image . '" alt="Image" border="0" />';
 ?>

And that's all, folks! Thanks for reading!
