What are potential pitfalls to avoid when using PHP/PDF classes for document generation?

One potential pitfall to avoid when using PHP/PDF classes for document generation is not properly handling errors or exceptions that may occur during the generation process. It is important to implement error handling mechanisms to gracefully handle any issues that may arise and prevent the generation process from failing unexpectedly.

try {
    // PDF generation code here
} catch (Exception $e) {
    echo 'An error occurred: ' . $e->getMessage();
}
