使用PHP将两个或多个base64代码合并到一个PDF中

I have two or more variables that have base64 values which are PDFs. Is there anyway that I can merge all my variables and they become one PDF, beacause it is impossible to download more than 1 PDF via HTTP.

I will be really thankfull for your answers.

Old question but my solution. I found and use http://www.fpdf.org/en/script/script94.php

get base64 data from DB and create temp files, save names in one array.

$pdf = fopen ('../tmp/test'.$rowp['id'].'.pdf','w');
fwrite ($pdf,base64_decode($rowp['pdf']));
fclose ($pdf);
array_push($pdfs,'../tmp/test'.$rowp['id'].'.pdf');

then for names in the array

$merge->add($pdfs[$i]); //add next file
unlink($pdfs[$i]); //clear temp one

finally output to the browser

$merge->output();
