[wordpress] Get cart item name, quantity all details woocommerce

Since WooCommerce 2.1 (2014) you should use the WC function instead of the global. You can also call more appropriate functions:

foreach ( WC()->cart->get_cart() as $cart_item ) {
   $item_name = $cart_item['data']->get_title();
   $quantity = $cart_item['quantity'];
   $price = $cart_item['data']->get_price();
   ...

This will not only be clean code, but it will be better than accessing the post_meta directly because it will apply filters if necessary.
