How can variables be transferred between two PHP files?

To transfer variables between two PHP files, you can use sessions or cookies. Sessions store data on the server side and can be accessed across multiple pages, while cookies store data on the client side. You can set variables in one PHP file and access them in another by either storing them in session variables or passing them through cookies. 

// File 1: set_variable.php
session_start();
$_SESSION['variable'] = "Hello, World!";

// File 2: get_variable.php
session_start();
echo $_SESSION['variable'];
