What are the best practices for handling multimedia content like music in PHP within a forum setting?

When handling multimedia content like music in a forum setting using PHP, it is important to properly sanitize and validate user inputs to prevent security vulnerabilities. Additionally, it is recommended to store multimedia files in a secure directory outside of the web root to prevent direct access. Utilizing PHP functions like `move_uploaded_file()` to handle file uploads and `htmlspecialchars()` to escape user inputs can help ensure the security and integrity of multimedia content in a forum setting. 

// Example code snippet for handling file upload of music in a forum setting
if ($_FILES['music_file']['error'] === UPLOAD_ERR_OK) {
    $uploadDir = 'uploads/music/';
    $uploadFile = $uploadDir . basename($_FILES['music_file']['name']);

    // Validate file type and size before moving it to the upload directory
    if ($_FILES['music_file']['type'] === 'audio/mpeg' && $_FILES['music_file']['size'] <= 5000000) {
        if (move_uploaded_file($_FILES['music_file']['tmp_name'], $uploadFile)) {
            echo "File is valid, and was successfully uploaded.";
        } else {
            echo "Upload failed.";
        }
    } else {
        echo "Invalid file type or size.";
    }
}
