PHP：按字母顺序对cookie进行排序？

Question

I've created a shopping cart where the products are stored in cookies, and I display all the cookies using this loop:

foreach($_COOKIE['products'] as $productId => $productQuantity) {

The problem is, every time add 1 to the quantity (so when I change the cookie value), that cookie ends up last in the list of the cart's products. How can I sort these cookies alphabetically, so the order will always be the same?

Many thanks!

Take a look at ksort .

It will do that, what you want.
