What are the best practices for tracking and limiting clicks on a bet link in PHP?

To track and limit clicks on a bet link in PHP, you can create a database table to store the click data and implement logic to check and limit the number of clicks allowed per user or per time period.

// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Get user IP address
$user_ip = $_SERVER['REMOTE_ADDR'];

// Check if user has clicked the link within a certain time period
$limit_time = time() - 3600; // 1 hour
$stmt = $conn->prepare("SELECT COUNT(*) FROM clicks WHERE user_ip = ? AND click_time > ?");
$stmt->bind_param("si", $user_ip, $limit_time);
$stmt->execute();
$stmt->bind_result($click_count);
$stmt->fetch();
$stmt->close();

if ($click_count < 5) {
    // Insert click data into database
    $stmt = $conn->prepare("INSERT INTO clicks (user_ip, click_time) VALUES (?, ?)");
    $stmt->bind_param("si", $user_ip, time());
    $stmt->execute();
    $stmt->close();

    // Redirect user to the bet link
    header("Location: http://www.betlink.com");
    exit;
} else {
    echo "You have reached the maximum number of clicks allowed.";
}

// Close database connection
$conn->close();
