What is the best practice for starting a session in PHP and why?

To start a session in PHP, the best practice is to call the session_start() function at the beginning of your script before any output is sent to the browser. This function initializes a session or resumes the current one, allowing you to store and retrieve session data across multiple pages on your website. 

<?php
session_start();

// Your PHP code here
?>
