How to randomise the display of 5 includes?

I, Brian · 09-14-2005, 10:06 AM

Sorry to ask a simple question, but I'm looking to randomise a display of images, which are called up with basic PHP include files.

So if there are 5 images, I'm calling them up as:

Code:


<!-- site content above --> 
<?PHP include("/home/user/public_html/image1.php"); ?> 
<?PHP include("/home/user/public_html/image2.php"); ?> 
<?PHP include("/home/user/public_html/image3.php"); ?> 
<?PHP include("/home/user/public_html/image4.php"); ?> 
<?PHP include("/home/user/public_html/image5.php"); ?> 
<!-- footer below -->

How would I randomise with a script within the body itself?

Many thanks for any replies.

Very basic:

PHP Code:


		
			
<?php

$i = rand(1,5);

include("/home/user/public_html/image" . $i . ".php");

?>

More flexible:

PHP Code:


		
			
<?php

// Insert image pages in this array

$image_pages = array("image1.php", "image2.php", "image3.php");



$arr_size = (count($image_pages) - 1);

$i = rand(0,$arr_size);



include("/home/user/public_html/" . $image_pages[$i]);

?>

Thanks for the reply - it does work, but I'll ideally looking for the files to be produced in a random order, rather than just one at random - is that possible with PHP?
