What is the difference between setting session names in .htaccess and using the session_name() function in PHP scripts?

Setting session names in .htaccess affects all PHP scripts on the server, while using the session_name() function in PHP scripts allows you to set session names on a per-script basis. This gives you more flexibility in managing session names based on specific requirements of each script.

<?php
session_name("custom_session_name");
session_start();

// Rest of your PHP code here
?>
