What are some common limitations of using fpdf and fpdi for generating PDFs in PHP?

One common limitation of using fpdf and fpdi for generating PDFs in PHP is the lack of support for certain advanced PDF features like interactive forms or multimedia elements. To address this limitation, you can consider using a more feature-rich library like TCPDF or mPDF which offer broader support for modern PDF functionalities.

// Example using TCPDF library to generate PDF with interactive form
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();

// Add interactive form elements
$pdf->SetFont('helvetica', '', 12);
$pdf->TextField('textfield', 50, 30, 100, 10, array('borderStyle' => 'solid', 'multiline' => true));

$pdf->Output('example.pdf', 'I');
