卸下車會話多維數組中的項

Question

林添加到購物車模塊工作，會話數組，我終於得到的是這樣的：

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 
         ) 

       ) 

     ) 

) 

我想從這個數組中刪除一個項目，說名稱爲「披薩」的商品。我該怎麼做？？

，那麼你應該只執行下面的代碼：

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