How can session data be passed between PHP files using the include() method?

Session data can be passed between PHP files using the include() method by ensuring that the session_start() function is called at the beginning of each PHP file where session data needs to be accessed. This will allow the files to share the same session data across them. Additionally, using $_SESSION superglobal array to store and retrieve session data will ensure that the data is accessible throughout the session. 

// File 1: session_start() should be called at the beginning
session_start();
$_SESSION['username'] = 'JohnDoe';

// File 2: include File 1 and access session data
session_start();
include('file1.php');
echo $_SESSION['username'];
