What is the correct placement of session_start in PHP scripts?

The correct placement of session_start() in PHP scripts is at the very beginning of the script, before any output is sent to the browser. This is important because session_start() initializes a new session or resumes an existing session, and any headers must be sent before any output to the browser. Placing session_start() at the beginning ensures that session data can be properly stored and accessed throughout the script. 

<?php
session_start();

// rest of your PHP code here
?>
