What are the best practices for embedding videos in PHP to prevent unauthorized downloads?

To prevent unauthorized downloads of embedded videos in PHP, one best practice is to use a combination of server-side authentication and encryption techniques. This can include checking user credentials before serving the video, using secure URLs with expiring tokens, and implementing DRM (Digital Rights Management) solutions to protect the video content. 

// Example code snippet for embedding a video with authentication and encryption
$user_authenticated = true; // Check user credentials here

if ($user_authenticated) {
    $video_url = 'https://example.com/video.mp4';
    $token = md5('secret_key' . time()); // Generate a unique token for the video URL
    $encrypted_url = $video_url . '?token=' . $token; // Append token to video URL
    echo '<video controls><source src="' . $encrypted_url . '" type="video/mp4"></video>';
} else {
    echo 'Unauthorized access.';
}
