What best practices should be followed to prevent output-related errors when working with PHP and generating PDF files?

To prevent output-related errors when working with PHP and generating PDF files, it is recommended to use output buffering to capture the PDF content before sending it to the browser. This helps to avoid any additional output being sent before the PDF content, which can cause errors in the PDF file. 

<?php
ob_start(); // Start output buffering

// PDF generation code here

$pdf_content = ob_get_clean(); // Get the buffered PDF content and clean the buffer

// Output the PDF content
header('Content-Type: application/pdf');
echo $pdf_content;
