How can one effectively extract form data from a PDF form in PHP and ensure all data is captured?

To effectively extract form data from a PDF form in PHP and ensure all data is captured, one can use a library like TCPDF or FPDI to parse the PDF file and extract the form fields. By iterating through the form fields, you can retrieve the data entered by the user and store it in an array or database for further processing. 

require_once('tcpdf/tcpdf.php');

// Path to the PDF file
$pdfFile = 'form.pdf';

// Create new PDF instance
$pdf = new TCPDF();
$pdf->setSourceFile($pdfFile);

// Get the number of pages in the PDF
$numPages = $pdf->getNumPages();

// Loop through each page to extract form data
for ($i = 1; $i <= $numPages; $i++) {
    $pdf->setPage($i);
    $formFields = $pdf->getFormFields();

    foreach ($formFields as $field => $value) {
        echo "Field: $field, Value: $value <br>";
    }
}
