What alternative methods, such as concat/fpdi, can be used to manipulate PDF pages in PHP?
One alternative method to manipulate PDF pages in PHP is by using the concat/fpdi library. This library allows you to merge multiple PDF files, add pages from one PDF to another, and manipulate existing pages. By using concat/fpdi, you can easily customize and manipulate PDF pages in your PHP application.
// Include the concat/fpdi library
require_once('fpdi/autoload.php');
// Create a new instance of the FPDI class
$pdf = new FPDI();
// Add a page from an existing PDF file
$pageCount = $pdf->setSourceFile('existing_file.pdf');
$templateId = $pdf->importPage(1);
$pdf->addPage();
$pdf->useTemplate($templateId);
// Output the modified PDF file
$pdf->Output('output_file.pdf', 'F');
