Are there any best practices or guidelines for handling headers in PHP when working with fpdf for PDF generation?

When working with fpdf for PDF generation in PHP, it is important to properly handle headers to ensure that the PDF file is generated correctly. One common issue is headers already being sent before fpdf can output the PDF content, resulting in errors or a corrupted PDF file. To solve this, you can use output buffering to capture the PDF content before sending any headers. 

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

require('fpdf.php'); // Include fpdf library

$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');

ob_end_clean(); // Clean (erase) the output buffer

$pdf->Output(); // Output the PDF content
?>
