What is the recommended way to pass variables between PHP files using sessions?

When passing variables between PHP files using sessions, the recommended way is to store the variables in the $_SESSION superglobal array. This array allows you to store variables that can be accessed across multiple PHP files during a user's session. To pass a variable from one PHP file to another, you can simply set the variable in one file and access it in another file using $_SESSION. 

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

// File 2: accessing the variable from session
session_start();
echo $_SESSION['variable_name']; // Output: value
