What is the recommended placement for the session_start() function in a PHP script?

The session_start() function in PHP should be placed at the very beginning of the script, before any output is sent to the browser. This ensures that session data can be properly initialized and accessed throughout the script. Failure to place session_start() at the beginning of the script may result in session-related errors or data not being stored correctly. 

<?php
session_start();

// Rest of your PHP code goes here
?>
