How can the issue of HTML content being appended to a downloaded file be resolved in PHP?

Issue: When downloading a file using PHP, HTML content may be appended to the downloaded file, causing corruption. To resolve this issue, we need to ensure that no HTML content is sent before initiating the file download. PHP Code Snippet: 

<?php
// Start the output buffer
ob_start();

// Your file download logic here

// Clear any previously echoed HTML content
ob_clean();

// Set appropriate headers for file download
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="example.txt"');

// Output the file content
echo "File content goes here";

// Flush the output buffer
ob_end_flush();
?>
