Is there a way to uniquely identify such website "visitors" using PHP, excluding those that mimic real visitors?

To uniquely identify website visitors using PHP, excluding those that mimic real visitors, we can utilize a combination of techniques such as setting cookies, tracking IP addresses, and implementing user-agent detection. By combining these methods, we can create a more robust visitor identification system that can help differentiate between real visitors and bots or automated scripts. 

// Check if the visitor has a cookie set
if(isset($_COOKIE['visitor_id'])) {
    $visitor_id = $_COOKIE['visitor_id'];
} else {
    // Generate a unique visitor ID
    $visitor_id = uniqid();
    setcookie('visitor_id', $visitor_id, time() + 86400 * 30); // Set cookie for 30 days
}

// Get visitor's IP address
$ip_address = $_SERVER['REMOTE_ADDR'];

// Get visitor's user-agent
$user_agent = $_SERVER['HTTP_USER_AGENT'];

// Store visitor information in a database or log file
// You can also use a combination of these values to create a unique identifier for each visitor
