What are the advantages of using PHP sessions over JavaScript for managing shopping cart data in an online shop?

When managing shopping cart data in an online shop, using PHP sessions is advantageous over JavaScript because PHP sessions are stored on the server-side, making them more secure and less susceptible to manipulation by users. Additionally, PHP sessions can easily handle complex data structures and can be accessed across multiple pages without the need for passing data through URLs or cookies. 

<?php
// Start a PHP session
session_start();

// Add an item to the shopping cart
$_SESSION['cart'][] = ['product_id' => 123, 'quantity' => 1];

// Retrieve shopping cart data
$cart = $_SESSION['cart'];

// Display shopping cart contents
foreach ($cart as $item) {
    echo 'Product ID: ' . $item['product_id'] . ', Quantity: ' . $item['quantity'] . '<br>';
}
?>
