How can PHP variables be securely passed between different files?

To securely pass PHP variables between different files, you can use sessions or cookies to store and retrieve the variables. Sessions are more secure as the data is stored on the server-side, while cookies store data on the client-side. You can set session variables in one file and access them in another file to securely pass information between them. 

// File 1: setting session variable
session_start();
$_SESSION['variable_name'] = $value;

// File 2: accessing session variable
session_start();
$value = $_SESSION['variable_name'];
