PHP - Simple Ad Rotation Script

PHP - Simple Ad Rotation Script


In this script (very easy script), we setup 3 ads for rotation. First ad, we want it to display 70%, second ad we want to display 20% and the last one we want to display 10% 


What to do
1. Random number 1-100
if result = 1-70 (we have opportunity to display ad1, 70%)
if result = 71-90 (we have opportunity to display ad2, 20%)
if result = 91-100 (we have opportunity to display ad3, 10%)


Example
In this script, we use rand(1, 100); to random number between 1 -100 and keep the result in variable named "$result_random" if result = 85 ad2 will be displayed.


Code - 


<?php 


// random number 1 - 100 $result_random = rand(1, 100); 


// if result less than or equal 70, display ad1 (70%) 
if($result_random <= 70){ 
echo "Display ad1"; 
} 


// if result less than or equal 90, display ad2 (20%) 
else if($result_random <= 90){ 
echo "Display ad2"; 
} 


// if result less than or equal 100, display ad3 (10%) 
else { 
echo "Display ad3"; 
} 


?>
