What are some potential methods for accurately tracking a user's visit duration on a PHP-based b2b portal?

One potential method for accurately tracking a user's visit duration on a PHP-based b2b portal is to use session variables to store the timestamp when the user first accesses the portal and then calculate the duration when the session ends. By comparing the current timestamp with the initial timestamp, you can determine the duration of the visit. 

// Start the session
session_start();

// Check if the user has accessed the portal before
if(isset($_SESSION['start_time'])){
    $start_time = $_SESSION['start_time'];
    $current_time = time();
    $visit_duration = $current_time - $start_time;
    
    // Display the visit duration in seconds
    echo "Visit duration: " . $visit_duration . " seconds";
} else {
    // Set the initial timestamp when the user first accesses the portal
    $_SESSION['start_time'] = time();
}
