In what ways can PHP developers optimize their code for handling radio button selections across multiple forms and pages, especially in the context of a content management system like xt:commerce?

When dealing with radio button selections across multiple forms and pages in a content management system like xt:commerce, PHP developers can optimize their code by using session variables to store the selected values. By storing the selected radio button values in session variables, developers can ensure that the selections persist across different pages and forms without the need to constantly pass them as parameters. 

// Start the session
session_start();

// Check if a radio button value has been submitted
if(isset($_POST['radio_button'])){
    // Store the selected radio button value in a session variable
    $_SESSION['selected_radio_button'] = $_POST['radio_button'];
}

// Retrieve the selected radio button value from the session
$selected_radio_button = isset($_SESSION['selected_radio_button']) ? $_SESSION['selected_radio_button'] : '';

// Use the selected radio button value in your code
echo "Selected radio button value: " . $selected_radio_button;
