Are there any best practices for handling directory listings in PHP?

When handling directory listings in PHP, it is important to ensure that sensitive information is not exposed to the public. One common best practice is to disable directory listings altogether to prevent users from accessing files they shouldn't see. This can be done by setting the `Options -Indexes` directive in the `.htaccess` file or using PHP to handle directory listings and only display approved files. 

<?php
// Disable directory listing
header("HTTP/1.1 403 Forbidden");
exit("403 Forbidden - Directory listing disabled");
?>
