從購物車會話多維數組中刪除項目

Question

我正在添加到購物車模塊，我最終得到的會話數組是這樣的：

    Array
(
    [cart] => Array
        (
            [0] => Array
                (
                    [item] => Array
                        (
                            [item_name] => burger
                            [item_price] => 5
                            [item_qty] => 3
                        )

                )

            [1] => Array
                (
                    [item] => Array
                        (
                            [item_name] => pizza
                            [item_price] => 15
                            [item_qty] => 2
                        )

                )

            [2] => Array
                (
                    [item] => Array
                        (
                            [item_name] => french fries
                            [item_price] => 8
                            [item_qty] => 5
                        )

                )

        )

)

我想從此數組中刪除一個項目，例如說名稱為“ pizza”的項目。 我該怎么做？？

Answer 1

function rem_from_array(&$session_array, $name)
{
  foreach($session_array as $key=>$elem)
    if($elem['item']['item_name']==$name)
    {
      unset($session_array[$key]);

      return;
    }
}

那么您應該只執行以下代碼：

rem_from_array($_SESSION['cart'], 'pizza');
