How can server-side observation be used to track the display location of a generated image in PHP?

Server-side observation can be used to track the display location of a generated image in PHP by logging the HTTP referrer header when the image is requested. This header contains the URL of the page where the image is being displayed. By capturing and storing this information in a database or log file, you can track the display location of the image. 

// Check if the HTTP referrer header is present
if(isset($_SERVER['HTTP_REFERER'])) {
    $referrer = $_SERVER['HTTP_REFERER'];
    
    // Log the referrer URL in a database or log file
    // For example, using MySQL
    $conn = new mysqli($servername, $username, $password, $dbname);
    $sql = "INSERT INTO image_display_locations (referrer) VALUES ('$referrer')";
    $conn->query($sql);
    $conn->close();
}
