How can session variables be effectively managed in PHP?

Session variables in PHP can be effectively managed by using the $_SESSION superglobal array to store and retrieve data throughout a user's session. To ensure proper management, it's important to start the session at the beginning of each PHP script using session_start() and then set or retrieve session variables using $_SESSION['variable_name']. Additionally, make sure to destroy the session when it's no longer needed using session_destroy(). 

<?php
// Start the session
session_start();

// Set session variable
$_SESSION['username'] = 'JohnDoe';

// Retrieve session variable
$username = $_SESSION['username'];

// Destroy the session when no longer needed
session_destroy();
?>
