Randomising Advertisments

Hi there,

I have about five advertisements on my website which are displayed down the side of my website, one below the other.

What I'm wanting to do is randomise they order in which they display in. How would I do this?

Store them in an array and play around with array_rand()

Thanks mr tech.

I tried the example code but it only showed two at a time so I modified the code to this:

PHP Code:


		
			
<?php

srand((float) microtime() * 10000000);

$input = array("Neo", "Morpheus", "Trinity", "Cypher", "Tank");

$rand_keys = array_rand($input, 5);

echo $input[$rand_keys[0]] . "\n";

echo $input[$rand_keys[1]] . "\n";

echo $input[$rand_keys[2]] . "\n";

echo $input[$rand_keys[3]] . "\n";

echo $input[$rand_keys[4]] . "\n";

?>

But it no longer changes... Any ideas why it's not working?

Thanks

Ben

I've tried it on my site and it works fine... No idea why it's not working for you...
