FPDF错误：此文档（testcopy.pdf）可能使用FPDI附带的免费解析器不支持的压缩技术

Question

I am running the following code and giving me this error : FPDF error: This document (testcopy.pdf) probably uses a compression technique which is not supported by the free parser shipped with FPDI. I used another pdf named test.pdf and that works fine but it is giving me error in testcopy.pdf.

I think this is parser problem. Anyone know any other parser that can be used with fpdf to avoid this error?

My code:

require('fpdf17/fpdf.php'); 
require('fpdf17/fpdi.php'); 
// initiate FPDI 
$pdf = new FPDI(); 
while (ob_get_level())
ob_end_clean();
header("Content-Encoding: None", true);
// set the sourcefile 
$pagecount = $pdf->setSourceFile('testcopy.pdf');

I want to split pdf in two pdfs and want to attach both pdfs in file attachments field.How to save pdf to server. Can it be possible with fpdf?

Answer 1

I had a very similar error like you. My solution was to convert the pdf to a lower pdf version. Than everything worked like expected.

I hope that simple trick will help you!
