How can one ensure that the browser initiates a download when using Content-Disposition: attachment in PHP?

To ensure that the browser initiates a download when using Content-Disposition: attachment in PHP, you need to set the appropriate headers in the PHP script. This includes setting the Content-Type header to the appropriate MIME type of the file being downloaded and adding the Content-Disposition header with the value "attachment". Additionally, you should output the file contents using readfile() or a similar function to force the browser to download the file. 

<?php
// Set the file path
$file = 'path/to/your/file.pdf';

// Set the appropriate MIME type
header('Content-Type: application/pdf');

// Force the browser to download the file
header('Content-Disposition: attachment; filename="' . basename($file) . '"');

// Output the file contents
readfile($file);
?>
