How can one troubleshoot and debug issues related to PDF manipulation in PHP, especially when encountering errors like the one described in the thread?

Issue: When manipulating PDF files in PHP, errors may occur due to incorrect file paths, missing libraries, or incorrect permissions. To troubleshoot and debug these issues, check the file paths, ensure that the required libraries (like TCPDF or FPDF) are properly installed, and verify the file permissions. Additionally, logging errors and using try-catch blocks can help identify and handle any issues that arise during PDF manipulation. 

<?php

// Example code snippet for troubleshooting PDF manipulation in PHP

// Check file path
$pdfFilePath = 'path/to/pdf/file.pdf';
if (!file_exists($pdfFilePath)) {
    die('PDF file not found');
}

// Require TCPDF library
require_once('tcpdf/tcpdf.php');

// Create new TCPDF object
$pdf = new TCPDF();

// Try to load the PDF file
try {
    $pdf->setSourceFile($pdfFilePath);
} catch (Exception $e) {
    die('Error loading PDF file: ' . $e->getMessage());
}

// Add your PDF manipulation code here

// Output the PDF
$pdf->Output('output.pdf', 'D');

?>
