Can PHP be used to fill out PDF forms?

Yes, PHP can be used to fill out PDF forms by using libraries such as FPDM or TCPDF. These libraries allow you to read an existing PDF form, fill in the fields with data, and save the filled-out form as a new PDF file.

// Example using FPDM library to fill out PDF form
require('fpdm/fpdm.php');

// Path to the existing PDF form
$pdf = new FPDM('form.pdf');

// Set the form data
$data = array(
    'field1' => 'Value 1',
    'field2' => 'Value 2',
    // Add more fields as needed
);

// Fill out the form with the data
$pdf->Load($data, false);
$pdf->Merge();
$pdf->Output('filled_form.pdf', 'F');
