title: Merging two PDF using PHP (for version > 1.4)
body: <p>I have a issue of merging two pdf into one pdf. I am using FPDF + FPDI and also tried TCPDF + FPDI, However i had a problem when I am using pdf version > 1.4 The php error is : FPDF error: This document (pdf_dump/1407303457.pdf) probably uses a compression technique which is not supported by the free parser shipped with FPDI.</p>
  
  <p>I do not want to use the commercial plugin of fpdi. Is there any work around available to work with pdf > 1.4 version.</p>
  
  <p>NB: I am using codeigniter</p>
  
  <p>Thank you.</p>
