Are there any best practices for managing and tracking visitor data over multiple days in PHP?

Managing and tracking visitor data over multiple days in PHP can be achieved by storing the data in a database, such as MySQL, and using cookies or sessions to maintain the visitor's information across different days. By storing the necessary data in a database and using cookies or sessions, you can easily track and manage visitor data over time. 

// Start a session to store visitor data
session_start();

// Check if visitor data exists in session, if not, create a new entry
if (!isset($_SESSION['visitor_data'])) {
    $_SESSION['visitor_data'] = [
        'visits' => 1,
        'last_visit' => date('Y-m-d H:i:s')
    ];
} else {
    // Update visitor data for each visit
    $_SESSION['visitor_data']['visits']++;
    $_SESSION['visitor_data']['last_visit'] = date('Y-m-d H:i:s');
}

// Display visitor data
echo 'Total Visits: ' . $_SESSION['visitor_data']['visits'];
echo 'Last Visit: ' . $_SESSION['visitor_data']['last_visit'];
