Banner and link rotationI
have many web sites and on most of them I run all kind of link/banner
exchange or affiliate programs. Some of the affiliate programs perform
much better and others are not that good. However, you will need a lot
of time to find out which one perform better than the others. You will
have to put a banner for the 1st affiliate program for few days and
analyze its performance results. Then you will have to do the same for
the other affiliate banners and at the end to choose the best one. Of
course if you have 5 different banners you will need to spend 5 x 3
days each = 15 days to find out which one is the best.
What I would suggest is to randomly show all the banners during the
first 3 days. At the end you will have the impressions, clicks, sales
results for all of the banners and you can decide which one to use a
lot sooner.
Now, what I am going to do is define PHP array with all the 5
affiliate codes. Then using the PHP rand(min,max) function I will
randomly select one of these 5 array elements. The first parameter
defines the minimum value that you want and the second parameter is for
the maximum value that you want generated. In our case we need to use
rand(1,5). All that has to be done now is to print the randomly
selected array element.
 $mybanners[1] ='<a href="http://www.programmerkingdom.com"><img src="banner1.jpg"></a>';
$mybanners[2] ='<a href="http://www.programmerkingdom.com"><img src="banner1.jpg"></a>';
$mybanners[3] ='<a href="http://www.programmerkingdom.com"><img src="banner1.jpg"></a>';
$mybanners[4] ='<a href="http://www.programmerkingdom.com"><img src="banner1.jpg"></a>';
$mybanners[5] ='<a href="http://www.programmerkingdom.com"><img src="banner1.jpg"></a>';
$id = rand(1,5);
echo $mybanners[$id];
?>
