How can sessions be properly handled when including PHP files with parameters?

When including PHP files with parameters, it is important to properly handle sessions to ensure that the parameters are passed correctly and securely. One way to do this is to store the parameters in session variables before including the file, and then retrieve them within the included file. This way, the parameters can be accessed throughout the session without the need to pass them as parameters each time the file is included.

// Store parameters in session variables before including the file
$_SESSION['param1'] = $param1;
$_SESSION['param2'] = $param2;

// Include the file
include 'file.php';

// Inside file.php, retrieve the parameters from session variables
$param1 = $_SESSION['param1'];
$param2 = $_SESSION['param2'];

// Now you can use $param1 and $param2 within file.php
