What is the recommended approach for handling sessions in PHP, according to the responses in the thread?

The recommended approach for handling sessions in PHP is to start the session using session_start() at the beginning of each PHP script that needs to access session variables. It is important to set session variables using $_SESSION['variable_name'] and unset them when they are no longer needed. Finally, remember to destroy the session using session_destroy() when the user logs out or the session expires.

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

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

// Unset session variables
unset($_SESSION['username']);

// Destroy the session
session_destroy();
?>
