What are the potential performance implications of using SESSION, COOKIE, or Web Storage for storing cart content in PHP?

Using SESSION to store cart content in PHP can lead to performance issues if the cart data becomes too large, as it is stored on the server and can impact server resources. Storing cart content in a COOKIE can also slow down performance, as each request will include the entire cart data in the headers. Web Storage can be a better option for storing cart content as it is stored locally on the client side, reducing server load and improving performance. 

// Storing cart content in Web Storage
<script>
// Save cart content to localStorage
var cart = {item1: 'Product 1', item2: 'Product 2'};
localStorage.setItem('cart', JSON.stringify(cart));

// Retrieve cart content from localStorage
var retrievedCart = JSON.parse(localStorage.getItem('cart'));
console.log(retrievedCart);
</script>
