WooCommerce sort cart items by variation addon values - php

Question

I need to sort my cart items by variation addon values.
For example I have 5 items in cart, and they have variation date:
first item date - 2016-05-05;
second 2016-05-08;
third 2016-05-20 and so on.
How can I sort them in cart ? I found that all info are in $cart_item[‘addons’] , but don’t find solution for how to sort them.
I editing my cart.php
<?php
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
$_product = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );
$product_id = apply_filters( 'woocommerce_cart_item_product_id', $cart_item['product_id'], $cart_item, $cart_item_key );
if ( $_product && $_product->exists() && $cart_item['quantity'] > 0 && apply_filters( 'woocommerce_cart_item_visible', true, $cart_item, $cart_item_key ) ) {
?>
