Okay I've had so many ideas on how to do probability but when it comes to practice it's a little more difficult than I thought. Okay so what I am trying to create is a random advertisements script. So far I have this:
public function adImage(){
$adimgLink[1] = 'template/template_files/ad_images/adhere.jpg';
$noAds = (count($adimgLink));
$randAd = rand(1,$noAds);
echo '<img src="'.$adimgLink[$randAd].'" />';
}
This works, however, I want it so customers can have a higher or lower probability of showing up depending on their budget they wish to spend on their advertisement. Any ideas? all help is appreciated =)
