How can session variables be passed between different PHP pages effectively?

To pass session variables between different PHP pages effectively, you can simply start the session on each page using session_start() at the beginning of the code. This allows you to set session variables on one page and access them on another by ensuring the session is active throughout the user's interaction with the website. 

// On the first page where you want to set session variable
<?php
session_start();
$_SESSION['username'] = 'JohnDoe';
?>

// On the second page where you want to access the session variable
<?php
session_start();
echo $_SESSION['username']; // Output: JohnDoe
?>
