Simple Visitor Tracking System in PHP + MySQL-Free Download

Here’s a complete visitor tracking system in PHP + MySQL that logs the following fields:

Visitor IP
Country (via a free IP API)
Date & Time
Browser & Device
Referrer Source (e.g., Facebook, Google, Direct)
Unique ID
Page Visited (logged on every page)

✅ 1. MySQL Table Structure

CREATE TABLE visitor_logs (
    id INT AUTO_INCREMENT PRIMARY KEY,
    visitor_id VARCHAR(100),
    ip_address VARCHAR(45),
    country VARCHAR(100),
    browser VARCHAR(255),
    device VARCHAR(255),
    referrer TEXT,
    page_visited TEXT,
    visit_time DATETIME
);

✅ 2. PHP Visitor Logger Script

Create a file: visitor_logger.php

<?php
function getUserIP() {
    return $_SERVER['REMOTE_ADDR'] ?? 'UNKNOWN';
}

function getBrowser() {
    $agent = $_SERVER['HTTP_USER_AGENT'];
    if (strpos($agent, 'Firefox') !== false) return "Firefox";
    elseif (strpos($agent, 'Chrome') !== false) return "Chrome";
    elseif (strpos($agent, 'Safari') !== false) return "Safari";
    elseif (strpos($agent, 'MSIE') !== false || strpos($agent, 'Trident/7') !== false) return "Internet Explorer";
    else return "Other";
}

function getDevice() {
    $agent = $_SERVER['HTTP_USER_AGENT'];
    if (preg_match('/mobile/i', $agent)) return "Mobile";
    elseif (preg_match('/tablet/i', $agent)) return "Tablet";
    else return "Desktop";
}

function getCountry($ip) {
    $details = @json_decode(file_get_contents("http://ip-api.com/json/$ip"));
    return $details && $details->status == 'success' ? $details->country : "Unknown";
}

function getReferrer() {
    return $_SERVER['HTTP_REFERER'] ?? "Direct";
}

function generateVisitorID() {
    return bin2hex(random_bytes(8));
}

function trackVisitor($pdo) {
    $visitor_id = $_COOKIE['visitor_id'] ?? generateVisitorID();
    if (!isset($_COOKIE['visitor_id'])) {
        setcookie('visitor_id', $visitor_id, time() + (86400 * 30), "/");
    }

    $ip        = getUserIP();
    $country   = getCountry($ip);
    $browser   = getBrowser();
    $device    = getDevice();
    $referrer  = getReferrer();
    $page      = $_SERVER['REQUEST_URI'];
    $time      = date('Y-m-d H:i:s');

    $stmt = $pdo->prepare("INSERT INTO visitor_logs (visitor_id, ip_address, country, browser, device, referrer, page_visited, visit_time)
                           VALUES (?, ?, ?, ?, ?, ?, ?, ?)");
    $stmt->execute([$visitor_id, $ip, $country, $browser, $device, $referrer, $page, $time]);
}

// DB Connection
$pdo = new PDO("mysql:host=localhost;dbname=your_db_name", "your_username", "your_password");
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

trackVisitor($pdo);
?>

✅ 3. Include Logger on Every Page

At the very top of every page (before any output):

<?php include_once "visitor_logger.php"; ?>

✅ Optional: View Logs (Admin Panel)

Create a simple admin.php:

<?php
$pdo = new PDO("mysql:host=localhost;dbname=your_db_name", "your_username", "your_password");
$logs = $pdo->query("SELECT * FROM visitor_logs ORDER BY visit_time DESC")->fetchAll(PDO::FETCH_ASSOC);
?>
<!DOCTYPE html>
<html>
<head>
    <title>Visitor Logs</title>
    <style>
        table { border-collapse: collapse; width: 100%; }
        th, td { padding: 8px; border: 1px solid #ccc; }
        th { background: #f4f4f4; }
    </style>
</head>
<body>
<h2>Visitor Logs</h2>
<table>
    <thead>
        <tr>
            <th>ID</th><th>Visitor ID</th><th>IP</th><th>Country</th><th>Browser</th>
            <th>Device</th><th>Referrer</th><th>Page</th><th>Date & Time</th>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($logs as $log): ?>
        <tr>
            <td><?= $log['id'] ?></td>
            <td><?= $log['visitor_id'] ?></td>
            <td><?= $log['ip_address'] ?></td>
            <td><?= $log['country'] ?></td>
            <td><?= $log['browser'] ?></td>
            <td><?= $log['device'] ?></td>
            <td><?= $log['referrer'] ?></td>
            <td><?= $log['page_visited'] ?></td>
            <td><?= $log['visit_time'] ?></td>
        </tr>
        <?php endforeach; ?>
    </tbody>
</table>
</body>
</html>

⚠ Notes:

Make sure your hosting allows file_get_contents() for external API (or use cURL if needed).
The ip-api.com service is free for non-commercial use with limits. For production, consider a paid IP geolocation API.
