What are some recommended resources for beginners to learn about PHP sessions and variable sharing?

PHP sessions are used to store user data across multiple pages on a website. To start a session, you use the session_start() function at the beginning of your PHP file. Variables can be shared across pages by storing them in the $_SESSION superglobal array. 

<?php
session_start();

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

// Access the session variable on another page
echo $_SESSION['username'];
?>
