Are there best practices for managing global variables and constants in external libraries like TCPDF in PHP?

When managing global variables and constants in external libraries like TCPDF in PHP, it is best practice to encapsulate them within a class to prevent conflicts with other parts of your application. By creating a class specifically for handling these variables and constants, you can ensure they are properly scoped and organized. This approach also makes it easier to manage and maintain these values in the future. 

class TCPDFConfig {
    const TCPDF_FONT = 'helvetica';
    const TCPDF_FONT_SIZE = 12;
    
    public static function getFont() {
        return self::TCPDF_FONT;
    }
    
    public static function getFontSize() {
        return self::TCPDF_FONT_SIZE;
    }
}

// Usage example
$font = TCPDFConfig::getFont();
$fontSize = TCPDFConfig::getFontSize();
