How can PHP be used to implement a banner rotation script that takes into account the referrer's banner ID?

To implement a banner rotation script that takes into account the referrer's banner ID, you can use PHP to store the banner IDs in an array and track the referrer's ID through a query parameter or session variable. Then, you can rotate the banners based on the referrer's ID to display the appropriate banner. 

<?php
// Define an array of banner IDs
$banners = array(1, 2, 3, 4);

// Get the referrer's banner ID from query parameter or session variable
$referrer_banner_id = $_GET['referrer_banner_id'];

// Rotate the banners based on the referrer's ID
$banner_index = array_search($referrer_banner_id, $banners);
if($banner_index !== false) {
    $next_banner_index = ($banner_index + 1) % count($banners);
    $next_banner_id = $banners[$next_banner_index];
} else {
    // Default to the first banner if referrer's ID is not found
    $next_banner_id = $banners[0];
}

// Display the banner based on the next banner ID
echo '<img src="banner_' . $next_banner_id . '.jpg" alt="Banner ' . $next_banner_id . '">';
?>
