How can PHP be used to track user activity on a website without affecting the browsing experience?

To track user activity on a website without affecting the browsing experience, you can use PHP to log relevant information such as page views, clicks, and other interactions to a database or a log file. This can be done asynchronously by sending the data in the background without delaying the loading of the webpage. By implementing this tracking system, you can gather valuable insights into user behavior without impacting the user's browsing experience. 

<?php
// Log user activity asynchronously
$activity_data = array(
    'user_id' => $_SESSION['user_id'],
    'page_url' => $_SERVER['REQUEST_URI'],
    'timestamp' => time()
);

$activity_json = json_encode($activity_data);

// Send activity data to a separate PHP script using cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/log_activity.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array('activity_data' => $activity_json));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
?>
