When creating a computer configurator in PHP, how can the selected component's price be accurately added to the base price without cumulative errors?

To accurately add the selected component's price to the base price without cumulative errors, you can store the base price in a session variable and update it each time a new component is selected. This way, the calculations will always be based on the original base price plus the prices of the selected components. 

<?php
session_start();

// Initialize base price
if (!isset($_SESSION['base_price'])) {
    $_SESSION['base_price'] = 0;
}

// Update base price with selected component's price
$selected_component_price = 50; // Replace with actual price calculation
$_SESSION['base_price'] += $selected_component_price;

// Display total price
echo 'Total Price: $' . $_SESSION['base_price'];
?>
