How can the PHP script be modified to handle dynamic file URLs, such as those with parameters like "dl.php?id=882"?

When handling dynamic file URLs with parameters like "dl.php?id=882", the PHP script can use the $_GET superglobal array to retrieve the parameter value and dynamically generate the file path based on that value. This can be achieved by modifying the script to extract the parameter value from the URL and use it to construct the file path. 

<?php
// Get the parameter value from the URL
$id = $_GET['id'];

// Construct the file path based on the parameter value
$file_path = 'files/' . $id . '.pdf';

// Output the file
header('Content-Type: application/pdf');
readfile($file_path);
?>
