How can PHP sessions be utilized to store and manage GET parameters for improved functionality?

When using GET parameters in a PHP application, the parameters are typically appended to the URL and can be accessed through the $_GET superglobal. However, if we want to store and manage these parameters across different pages or requests, we can utilize PHP sessions. By storing the GET parameters in session variables, we can maintain their values throughout the user's session, allowing for improved functionality and ease of access. 

<?php
// Start the session
session_start();

// Check if GET parameters exist and store them in session variables
if(isset($_GET['parameter1'])) {
    $_SESSION['parameter1'] = $_GET['parameter1'];
}
if(isset($_GET['parameter2'])) {
    $_SESSION['parameter2'] = $_GET['parameter2'];
}

// Access the stored parameters from session variables
if(isset($_SESSION['parameter1'])) {
    $parameter1 = $_SESSION['parameter1'];
}
if(isset($_SESSION['parameter2'])) {
    $parameter2 = $_SESSION['parameter2'];
}

// Now you can use $parameter1 and $parameter2 throughout the user's session
?>
