How can PHP be used to create and store PDF files for download?

To create and store PDF files for download using PHP, you can use a library like TCPDF or FPDF to generate the PDF file, then save it to a directory on your server. You can then provide a download link to the saved PDF file on your website.

// Include the TCPDF library
require_once('tcpdf/tcpdf.php');

// Create new PDF document
$pdf = new TCPDF();

// Set document information
$pdf->SetCreator('Your Name');
$pdf->SetAuthor('Your Name');
$pdf->SetTitle('Title of the PDF');

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

// Set some content
$pdf->SetFont('Arial', '', 12);
$pdf->Write(0, 'Hello, World!');

// Save the PDF to a file
$pdf->Output('pdfs/your_pdf_file.pdf', 'F');

// Provide a download link to the saved PDF file
echo '<a href="pdfs/your_pdf_file.pdf" download>Download PDF</a>';
