Are there alternative methods or libraries in PHP that allow for creating PDF documents with form input fields?

To create PDF documents with form input fields in PHP, one alternative method is to use the TCPDF library, which allows for the creation of interactive PDF forms. With TCPDF, you can easily add form fields such as text fields, checkboxes, and radio buttons to your PDF documents. By using this library, you can generate PDF files with interactive form elements that users can fill out and submit.

require_once('tcpdf/tcpdf.php');

// Create new TCPDF object
$pdf = new TCPDF();

// Set document information
$pdf->SetCreator('TCPDF');
$pdf->SetAuthor('Author');
$pdf->SetTitle('Title');
$pdf->SetSubject('Subject');
$pdf->SetKeywords('Keywords');

// Add a page
$pdf->AddPage();

// Add a form field
$pdf->TextField('textfield1', 50, 20, array('borderStyle' => 'solid', 'borderColor' => array(0, 0, 0)));

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