How can the use of extract($_SESSION['variable']) simplify the process of accessing session data in PHP?

Using extract($_SESSION['variable']) in PHP simplifies the process of accessing session data by extracting the values from the session variable into the current symbol table. This allows you to directly access the session variables as regular variables without having to use $_SESSION['variable'] every time. 

<?php
session_start();

$_SESSION['username'] = 'JohnDoe';
$_SESSION['email'] = 'johndoe@example.com';

extract($_SESSION);

echo $username; // Outputs: JohnDoe
echo $email; // Outputs: johndoe@example.com
?>
