How can PHP be utilized to display real-time visitor statistics, such as total visitors, current online users, and daily visitor counts, on a website?

To display real-time visitor statistics on a website using PHP, you can utilize sessions to track unique visitors, store timestamps of their last activity, and calculate the number of current online users. You can also store visitor data in a database to track total visitors and daily visitor counts. 

<?php
// Start or resume a session
session_start();

// Update last activity timestamp for the current visitor
$_SESSION['last_activity'] = time();

// Check if the current visitor is a new session
if(!isset($_SESSION['visited'])) {
    $_SESSION['visited'] = true;
    // Increment total visitors count in database
}

// Calculate number of current online users
$online_users = 0;
foreach($_SESSION as $key => $value) {
    if($key != 'last_activity' && $key != 'visited' && (time() - $value) <= 60) {
        $online_users++;
    }
}

// Display visitor statistics
echo "Total Visitors: "; // Retrieve total visitors count from database
echo "Current Online Users: " . $online_users;
echo "Daily Visitor Count: "; // Retrieve daily visitor count from database
?>
