What is the significance of using $_SESSION instead of $Session in PHP code for storing session variables?

Using $_SESSION instead of $Session in PHP code is significant because $_SESSION is a superglobal variable that is specifically designed for storing session variables in PHP. Using $Session could lead to errors or unexpected behavior as it is not a predefined variable in PHP. By using $_SESSION, you ensure that your session variables are properly stored and accessed throughout your PHP application. 

<?php
session_start();

// Storing a session variable using $_SESSION
$_SESSION['username'] = 'JohnDoe';

// Accessing the session variable
echo $_SESSION['username'];
?>
