What is the best way to secure a webcam stream and restrict access to specific users in PHP?

To secure a webcam stream and restrict access to specific users in PHP, you can implement user authentication and authorization mechanisms. This involves verifying the user's identity and permissions before allowing them to access the webcam stream. You can also use HTTPS to encrypt the stream and prevent unauthorized access.

// Check if user is authenticated and authorized to access webcam stream
session_start();

if (!isset($_SESSION['user_id'])) {
    header("Location: login.php");
    exit();
}

$allowed_users = ['user1', 'user2', 'user3']; // List of users allowed to access the webcam stream

if (!in_array($_SESSION['username'], $allowed_users)) {
    echo "You are not authorized to access this webcam stream.";
    exit();
}
