How can PHP be used to embed different file types, such as Excel, into a PDF container?

To embed different file types, such as Excel, into a PDF container using PHP, you can utilize a library like TCPDF or FPDF. These libraries allow you to create PDF documents and embed various file types within them. By converting the Excel file to an image or HTML format, you can then insert it into the PDF document using the library's functions.

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

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

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

// Embed an Excel file as an image
$pdf->Image('path_to_excel_file.jpg', 10, 10, 100, 100, 'JPG');

// Output the PDF
$pdf->Output('output.pdf', 'I');
