What alternative methods can be used to display HTML content and prompt a file download in separate steps?

When needing to display HTML content and prompt a file download in separate steps, one alternative method is to use a combination of PHP output buffering and the `header()` function to set the content type and file name for download. By buffering the HTML content first and then setting the appropriate headers for file download, you can achieve the desired behavior. 

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

// Display HTML content
echo "<html><body><h1>Hello, World!</h1></body></html>";

// Get buffered content
$html_content = ob_get_clean();

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

// Output the HTML content for download
echo $html_content;
