Are there any specific libraries or tools recommended for handling PDF form filling in PHP effectively?

When handling PDF form filling in PHP, one recommended library is TCPDF, which allows for creating and filling PDF forms programmatically. Another useful tool is FPDI, which can be used to import existing PDF forms and fill them with data. These libraries provide a straightforward way to work with PDF forms in PHP effectively.

// Example code using TCPDF to fill a PDF form
require_once('tcpdf_include.php');

$pdf = new TCPDF();
$pdf->setSourceFile('template.pdf');
$tplIdx = $pdf->importPage(1);

$pdf->AddPage();
$pdf->useTemplate($tplIdx, 0, 0, 210);

$pdf->SetFont('helvetica', '', 12);
$pdf->SetXY(50, 50);
$pdf->Write(0, 'John Doe');

$pdf->Output('output.pdf', 'D');
