推荐答案

我以前做过这个.我有一个用 fpdf 生成的 pdf，我需要向其中添加可变数量的 PDF.

I've done this before. I had a pdf that I generated with fpdf, and I needed to add on a variable amount of PDFs to it.

所以我已经有一个 fpdf 对象和页面设置(http://www.fpdf.org/)我使用 fpdi 导入文件(http://www.setasign.de/products/pdf-php-solutions/fpdi/)通过扩展PDF类添加FDPI:

So I already had an fpdf object and page set up (http://www.fpdf.org/) And I used fpdi to import the files (http://www.setasign.de/products/pdf-php-solutions/fpdi/) FDPI is added by extending the PDF class:

class PDF extends FPDI
{

} 



    $pdffile = "Filename.pdf";
    $pagecount = $pdf->setSourceFile($pdffile);  
    for($i=0; $i<$pagecount; $i++){
        $pdf->AddPage();  
        $tplidx = $pdf->importPage($i+1, '/MediaBox');
        $pdf->useTemplate($tplidx, 10, 10, 200); 
    }

这基本上使每个 pdf 成为一个图像，以放入您的其他 pdf.它非常适合我需要的用途.

This basically makes each pdf into an image to put into your other pdf. It worked amazingly well for what I needed it for.
