What best practices can be followed to ensure proper session management and avoid errors like "headers already sent" in PHP scripts?

Issue: The "headers already sent" error in PHP scripts occurs when output is sent to the browser before headers are set, typically caused by whitespace or HTML content before calling functions like session_start(). To avoid this error and ensure proper session management, it's important to make sure that session_start() is called before any output is sent to the browser. Code snippet: 

<?php
// Start the session at the beginning of the script
session_start();

// Your PHP code goes here
?>
