How can variables be passed between PHP files using sessions?

To pass variables between PHP files using sessions, you can store the variable in the $_SESSION superglobal array in one file and then access it in another file by starting the session and retrieving the variable from the $_SESSION array. 

// File 1: storing variable in session
session_start();
$_SESSION['myVariable'] = 'Hello, World!';

// File 2: accessing variable from session
session_start();
echo $_SESSION['myVariable']; // Output: Hello, World!
