Are there any best practices for enabling users to save webpage content in different file formats using PHP?

To enable users to save webpage content in different file formats using PHP, one best practice is to use the appropriate headers to set the content type and attachment disposition. This ensures that the browser prompts the user to download the file instead of displaying it in the browser window. Additionally, you can use PHP functions like file_put_contents() to save the webpage content to a file in the desired format. 

<?php
// Set the content type and attachment disposition
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="saved_content.txt"');

// Get the webpage content
$url = 'https://www.example.com';
$content = file_get_contents($url);

// Save the content to a file
file_put_contents('saved_content.txt', $content);
