Metator Cart
The simplest shopping cart class ever to exist. For a full stack shopping cart system, check out metator/application.
The cart class class is hopefully very intuitive. It depends on nothing, and assumes nothing except that your items have a unique identifier.
use Metator\Cart\Cart; $cart = new Cart; $cart->add(5); $cart->add(5); $cart->add(5); echo $cart->quantity(5); // 3 print_r($cart->items()); // array(5) $cart->remove(5); echo $cart->quantity(5); // 0 print_r($cart->items()); // array() $cart->add(5); $cart->setQuantity(5,500); echo $cart->quantity(5); // 500 $cart->setQuantity(5,0); print_r($cart->items()); // array()
##Understanding Identifiers## The value for the ID could be the auto_increment from your database, a product SKU, or any kind of unique identifier like a hash. For example if a T-Shirt comes in multiple colors but always has the same SKU & ID regardless of color, you could use a hash representing the configured state of that product for the id here.
