Are there alternative methods or libraries in PHP for processing PDF files and integrating them with database operations, considering the limitations of the FDF Toolkit SDK?

The FDF Toolkit SDK has limitations in processing PDF files and integrating them with database operations in PHP. To overcome these limitations, alternative methods or libraries can be used such as TCPDF, FPDI, or mPDF which provide more robust features for working with PDF files and databases in PHP.

// Example using TCPDF library to process PDF files and integrate with database operations
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', 'B', 16);
$pdf->Cell(40, 10, 'Hello World!');

// Save PDF file to server
$pdf->Output('example.pdf', 'F');

// Insert PDF file path into database
$pdfFilePath = 'example.pdf';
$insertQuery = "INSERT INTO pdf_files (file_path) VALUES ('$pdfFilePath')";
// Execute insert query using your preferred database connection method
