How can the PHP script be modified to count page views for specific subpages, not just the main domain?

To modify the PHP script to count page views for specific subpages, you can extract the subpage from the URL and use it as a key in the page views tracking array. This way, each subpage will have its own count. You can achieve this by using PHP's $_SERVER['REQUEST_URI'] to get the current URL and then extract the subpage from it.

// Get the current URL
$current_url = $_SERVER['REQUEST_URI'];

// Extract the subpage from the URL
$subpage = explode('/', $current_url)[1];

// Update the page views count for the specific subpage
if(isset($page_views[$subpage])) {
    $page_views[$subpage]++;
} else {
    $page_views[$subpage] = 1;
}

// Output the page views count for the specific subpage
echo "Page views for $subpage: " . $page_views[$subpage];
