Rotating Ad banner system

[Reef]

Hi, I'm a noob (so I'm expecting to be shot).

 

I've just started to learn PHP by myself however I am asking for help with something I need to get done asap really.

 

I want to set a rotating ad-banner so that when its on the site, it changes the image and link on every page load, upto 10 different images/links

 

Can anyone point me in the right direction ?

 

I would REALLY appreciate it

 

oh and if this is the wrong section - sorry.

For a random approach:

 

<?php
$banners = array('yahoo', 'google', 'live');
$rand = rand(0, count($banners)-1);
echo "<a href='http://www." . $banners[$rand] . ".com'><img src='banners/" . $banners[$rand] . ".jpg' /></a>";
?>

 

The $banners array holds the banners names, assuming u name your image files as a the sites link, so u spare some time and code (dont go on a lot of if statements).

 

For a real rotator, meaning that u need to go from banner1 to banner10 incrementaly each page reload, consider the following script:

 

<?php
session_start();
$banners = array('yahoo', 'google', 'live');
if(isset($_SESSION['position']) and $_SESSION['position'] != count($banners)-1){
$_SESSION['position']++;
} else{
$_SESSION['position'] = 0;
}
$bannerKey = $_SESSION['position'];
echo "<a href='http://www." . $banners[$bannerKey] . ".com'><img src='banners/" . $banners[$bannerKey] . ".jpg' /></a>";
?>

 

It uses sessions to keep track of the actual banner and increments it each reload. Like the first example, this uses an array for banner names. Feel free to try and modify it and ask for further help.
