What are common errors encountered when using FPDI in PHP, and how can they be resolved?
One common error encountered when using FPDI in PHP is "FPDF error: This document (source.pdf) probably uses a compression technique which is not supported by the free parser shipped with FPDI." This error occurs when the source PDF file is compressed using a method that FPDI does not support. To resolve this error, you can use the setSourceFile method with the $parse_mode parameter set to 'parse' to enable the parsing of compressed PDF files.
require_once('fpdf/fpdf.php');
require_once('fpdi/fpdi.php');
$pdf = new FPDI();
$pdf->setSourceFile('source.pdf', 'parse');
